Introduction Different Types of Security Threats

There are four main types of security threats: viruses, worms, Trojan horses, and spyware.

A virus belongs to the malware category that replicates itself and infects your system without your permission or knowledge. A worm is also a type of malware that can spread itself and cause damage. However, a worm does not need to attach itself to anything to function; it can simply spread through networks. On the other hand, a Trojan horse pretends to be something else to trick you into downloading or installing a particular program to infect your system. Spyware is a program to gather information about you or your business data without your knowledge or permission.

There are many other security threats beyond these four primary categories, but these are some of the most common.

How to Prevent Security Threats?

To prevent security threats, it is essential to take a proactive approach and be aware of the latest risks. In this regard, let’s take a look at a few globally followed vital steps to protect data from various security threats

Keep your software up to date

One of the immediate steps you can take to protect yourself from security threats is to ensure that your software is up to date. Consider upgrading your OS, browsers, and any other applications that you use. Outdated software can often have security vulnerabilities that attackers can exploit.

Most software programs will have an automated update feature that will check for new versions of the program and download them automatically. However, it’s also important to manually check for updates regularly. This ensures that you’re always using the latest software version, which will often include security patches for newly discovered vulnerabilities.

Sometimes, you may be prompted to update your software when you open it or try to use a specific feature. Following these prompts is essential as they usually indicate that a critical security update is available.

Of course, keeping your software up to date won’t protect you from all security threats, but it’s a simple and effective way to reduce your risk.

Use strong passwords

Using strong passwords is another crucial way to prevent security threats. Attackers often try brute force their way into accounts using co-shared password lists. Using strong and unique passwords can make the task much more impossible for hackers.

To create a strong password, use an ideal combination of letters (upper and lowercase), numbers, and symbols. The longer the password, the better. Another good idea is to use a phrase or series of words that are easy for you to remember but would be difficult for someone else to guess.

Of course, even the most robust password is only as good as the system it’s protecting. So make sure you’re also taking other steps to keep your accounts safe, such as enabling two-factor authentication whenever possible.

You can install an anti-spam plugin on your web browser. This will help to block most spammers from even reaching your computer.

You can report any spammy links that you come across.

By doing this, you can help to keep the internet safe for everyone.

Use security tools

There are many different security tools available that can help you protect your systems from attack. These tools can include antivirus software, firewalls, and intrusion detection systems. By using these tools, you can make it much harder for attackers to compromise your systems.

For instance, firewalls can block incoming traffic from known or suspected malicious sources. Antivirus software can scan files and email attachments for malware and remove any malware that is found. Intrusion detection systems can monitor network activity for suspicious activity and raise the alarm if such action is detected.

Using these and other security tools greatly significantly the risk of being compromised by a security threat.

Two-Way Authentication

In recent years, security threats have become increasingly sophisticated and challenging to detect. Two-way authentication is essential for top organizations at these threats.

Two-way authentication, also known as two-factor authentication, is a process whereby users must provide two forms of identification to invoice a system or service. It could involve using a password, a PIN, PINrint, and a retina scan.


In conclusion, security threats are a genuine and ever-present danger. If you’re running an online business or doing online transactions often, understanding the potential risks of cybercrime and how to protect yourself against them is more important than ever. Utilizing solutions such as two-factor authentication, frequent updating of software, and implementing adequate password policies can go a long way in helping you beat security threats before they become an issue. Additionally, staying informed about the latest cyber threats can help you stay one step ahead and ensure that your data remains safe from malicious actors.

We Already Know How To Beat Covid

All you hear about right now is masks, but in all the debate we may have temporarily forgotten about some other important ways of fighting off the coronavirus. New research from scientists in the Netherlands found that combining masks with hand washing and social distancing is crucial for limiting the spread of COVID-19. They published their findings in the journal PLOS Medicine this week. The researchers used computer modeling to examine how effective these protective measures are when used alone and when paired with government-mandated social distancing. They found that self-imposed actions like wearing a mask can have a major impact on preventing transmission—especially when most people in a community use them in tandem.

“If nearly all [the] population adopted self-imposed measures we would not have to confront the possibility of secondary lockdowns as well as the possibility that we may find our medical systems overwhelmed during the peaks of epidemics,” Ganna Rozhnova, an infectious disease modeler at the University Medical Center Utrecht in the Netherlands and coauthor of the new findings, said in an email to Popular Science. “Overall, it appears to be a relatively cheap solution that would not disrupt economical and societal fabric as much as a lockdown does.”

Rozhnova and her colleagues found that government-imposed social distancing measures—such as closing businesses, canceling events, and stay-at-home orders—can delay the peak of a COVID-19 epidemic by up to seven months on their own. When people choose to wear masks, wash their hands thoroughly, and continue to social distance after these restrictions are lifted, the peak of the epidemic can be delayed for several additional months and fewer people will become infected in total.

The more swiftly people become aware of the threat posed by COVID-19 and adopt these measures, the greater their impact. The researchers estimated that in a country where 90 percent of the population uses multiple actions such as hand washing and social distancing—even if they aren’t perfectly executed—a large outbreak of COVID-19 or a second wave of the epidemic could be averted.

There are a number of variables that Rozhnova and her team didn’t account for that could affect the accuracy of these predictions in the real world; people will vary in how much time they spend around others, and it’s not yet known whether people who recover from COVID-19 can become reinfected.

Still, the model that Rozhnova and her team developed “is very sophisticated,” says Brandye Nobiling, director of the Community Health Program at Salisbury University in Maryland, who was not involved with the research. The findings fit well with other research that suggests that these actions can play a huge role in limiting the spread of COVID-19.

“The preventative measures are worth it and the science is backing that up,” Nobiling says. “So why not do as much as we can do based on what we know about the efficacy of these measures?”

Even taken alone, these protective measures may prevent people from spreading COVID-19. On July 14, the Centers for Disease Control and Prevention published a report describing how two hair stylists in Missouri tested positive for COVID-19 and served 139 clients before taking leave from work. None of the clients developed symptoms and the 67 clients who were later tested for COVID-19 all received negative results. “Adherence to the community’s and company’s face-covering policy likely mitigated spread of SARS-CoV-2,” the researchers concluded.

However, the new findings point to the importance of using not just one but multiple safety precautions—even when businesses reopen and the initial waves of infection begin to ebb (though in the U.S., crucially, infections have not waned). “Individual behavior may be essential for changing the course of this epidemic, whereas temporary government-imposed interventions we experienced in the past months may have a high risk of an epidemic resurgence when lifted,” Rozhnova said.

5 Overlooked Threats To Cloud Computing

A lack of understanding about security risks is one of the key factors holding back cloud computing.

Viruses, malware and phishing are still concerns, but issues like virtual-machine-launched attacks, multi-tenancy risks and hypervisor vulnerabilities will challenge even the most up-to-date security administrator. Here are 5 overlooked threats that could put your cloud computing efforts at risk.

The days of security through obscurity are over. In the past, if you were an anonymous SMB, the threats you worried about were the typical consumer ones: viruses, phishing and, say, Nigerian 419 scams. Hackers didn’t have enough to gain to focus their energy on penetrating your network, and you didn’t have to worry about things like DDoS attacks – those were a service provider problem.

Remember the old New Yorker cartoon: “on the Internet no one knows you’re a dog”? Well, in the cloud, no one knows you’re an SMB.

“Being a small site no longer protects you,” said Marisa S. Viveros, VP of IBM Security Services. “Threats come from everywhere. Being in the U.S. doesn’t mean you’ll only be exposed to U.S.-based attacks. You – and everyone – are threatened from attackers from everywhere, China, Russia, Somalia.”

To a degree, that’s been the case for a while, but even targeted attacks are global now, and if you share an infrastructure with a higher-profile organization, you may also be seen as the beachhead that attackers can use to go after your bigger neighbors.

What this all adds up to is that in the cloud, DIY security no longer cuts it. Also, having an overworked general IT person coordinating your security efforts is a terrible idea.

As more and more companies move to cloud-based infrastructure, only the biggest companies with the deepest pockets will be able to handle security on their own. Everyone else will need to start thinking of security as a service, and, perhaps, eventually even a utility.

One way that security-wary companies get their feet wet in the cloud is by adopting private clouds. It’s not uncommon for enterprises to deploy private clouds to try to have it both ways. They get the cost and efficiency benefits of the cloud but avoid the perceived security risks of public cloud projects.

“Many ‘private’ cloud infrastructures are actually hosted by third parties, which still leaves them open to concerns of privileged insider access from the provider and a lack of transparency to security practices and risks,” said Geoff Webb, Director of Product Marketing for CREDANT Technologies, a data protection vendor.

Much of what you read about cloud security still treats it in outdated ways. At the recent RSA conference, I can’t tell you how many times people told me that the key to cloud security was to nail down solid SLAs that cover security in detail. If you delineate responsibilities and hold service providers accountable, you’re good to go.

There is some truth to that, but simply trusting a vendor to live up to SLAs is a sucker’s game. You – not the service provider – will be the one who gets blamed by your board or your customers when sensitive IP is stolen or customer records are exposed.

A service provider touting its security standards may not have paid very close attention to security. This is high-tech, after all, where security is almost always an afterthought.

Many companies, when building out their private or hybrid clouds, are hitting walls. The easy stuff has been virtualized, things like test development and file printing.

Multi-tenancy isn’t strictly a public cloud issue. Different business units – often with different security practices – may occupy the same infrastructure in private and hybrid clouds.

The Greatest Challenges & Threats In Seo

Insights from our recent State of SEO Survey report show that although the last year began with uncertainty across the industry, SEO is now more in demand than ever before.

Even so, it is not without its challenges. What issues are SEO professionals facing — and moving forward, what are the threats that might block success?

We surveyed over 2,800 SEO professionals about their experiences in SEO over the last 12 months. Keep reading to find out:

What the biggest challenges were in the last 12 months.

Whether SEO results trended better or worse over the last year.

What SEO pros perceive as the industry’s greatest threats in the years ahead.

What Were the Biggest Challenges in SEO Over the Last 12 Months?

At the start of the pandemic, there was a lot of uncertainty for everyone as businesses tried to navigate an unprecedented situation rife with real-world shutdowns, a near-instant shift to digital, and massive changes in consumer behavior.

As the pandemic unfolded many businesses had to pivot quickly in order to survive. Some struggled while others thrived as digital and ecommerce growth accelerated by several years.

Early in the pandemic, budget cuts were the biggest challenge for SEO professionals, as indicated by 37.6% of survey respondents.

Strategy issues (34.8%) were also a significant challenge in the SEO industry, as was a lack of resources (32.9%).

SEO Industry Challenge % # respondents Budget cuts 37.6% 874 Strategy issues 34.8% 810 Lack of resources 32.9% 765 Pandemic-related issue 27.9% 649 Management/stakeholders approval 27.3% 635 Alignment with other departments 26.9% 627 Scaling processes 25.8% 600 Client relationship issues 14.1% 327 Legal approval 10.6% 247 Not experienced any challenges 5.2% 120

(Question asked: In the last 12 months, what were your biggest challenges that blocked SEO success? Up to 3 options could be selected. Open to all respondents. Answered: 2,325; 1.76% selected “Other.”)

Across the industry, it appears that a lot of budgets were cut as an initial reaction, but many clients quickly came back on board. Out of those, many clients actually increased spend and invested more heavily in SEO.

Ron Lieback of Content Mender, for example, experienced cuts to client budgets and says, “Many cut their budgets due to losing their clients/customers, which meant a cut on new content and technical SEO monitoring.”

In combination with the complications of the pandemic, SEO professionals also had to contend with a series of core and major Google updates in 2023.

Those updates created plenty of disruption. Michael Bonfils of SEM International warns that we still haven’t seen the full effects of the recent Page Experience Update.

“Google continues to put a lot more emphasis on the ‘overall’ health of a site, so even if a site is perfectly optimized for SEO, it may not perform as well as it should (or its competitors) due to a weaker technical foundation, less paid efforts, weaker social signals, unfavorable link environment, etc.,” Bonfils explains.

He added, “We’re only seeing the first, mild consequences of the Page Experience Update and I can only assume that it’ll get much more important over time.”

Jason Barnard, the founder of Kalicube, experienced longer wait times for crawling. He shared with us that, “Google seems to have become less reactive to new and updated content, whether through the normal process of crawling, or submission through Search Console.”

He noted that this has led to longer wait times for seeing any effect of those changes, which is frustrating.

Are Results Getting Better or Worse for SEO?

Although budget cuts were the greatest challenge for the industry, results from SEO are getting better and better.

SEO results improved this year for 64.6% of respondents, with 18% reporting they were “a lot” more successful than the year prior.

(Question asked: In the last 12 months, compared to the year before, how do you rate the results from SEO? Open to all respondents, Answered: 2,369. 2.11% selected “not sure.”)

It is worth considering that many sites may have benefitted from the “rising tide floats all boats” effect as worldwide internet traffic levels increased by 40%.

As a result of restrictions on visits to physical stores, ecommerce saw the biggest leap of year-on-year growth in a decade with 32% growth driving $759.4 billion in U.S. ecommerce sales.

Digital businesses also had to contend with shifting spending patterns as consumers became more cautious spending on luxury goods.

Bonfils confirms that many of his clients noticed this shift in traffic due to users spending less on travel, luxury items, technology, etc. “Most spend went to essentials, personal items, and savings,” he said.

According to Google, the businesses that benefited most from the pandemic were home improvements, home fitness, pet-related, and anything work-from-home-related.

The Biggest Threats to SEO in the Next Two Years

Biggest Threat to SEO % # respondents 38.7% 899 Google updates 35.1% 817 Machine learning/AI 28.4% 660 Third-party cookies 22.9% 534 Messaging platforms (Whatsapp, Slack) 21.3% 495 Offline brand awareness (direct traffic) 17.8% 414 Government regulation 16.7% 388 GPT-3 16.1% 375 Apps 14.1% 327 Site security 13.7% 319 Email marketing 12.6% 294 Don’t think there are any 4.9% 115

(Question asked: In the next two years, what will be the biggest threat to SEO? Up to 3 options could be selected. Open to all respondents. Answered: 2,325. 1.2% selected “other.”)

The third greatest threat to SEO is from machine learning, as indicated by 28.4% of SEO professionals.

Lieback agrees that Google updates and AI pose threats and also thinks that a shortage of talent is going to be an issue, especially on the strategic side.

“I can hire people to implement and do the basics of work, but to find an SEO pro who truly understands the way everything works together – from on-page to off-page and a wise content marketing strategy – is nearly impossible,” he said.

It’s a challenge shared by many SEO experts, including Barnard. “I see, read, and hear super smart and talented people all over the place. But how there could ever really be enough supply for the potential demand?” he wondered.

Every website that comes online creates new demand for SEO, he noted.

“The question is, would that work be profitable? And that depends on the talent available,” Barnard added.

Right now, the shortage means that talented SEO professionals are in demand and are in a strong position for salary negotiations.

Our survey data shows that 60% of SEO professionals earn the same or more than the U.S. median, and SEO comes with a $100,000+ salary for 19%. Learn more in our SEO Salary Report 2023: How Much SEO Pros Get Paid.

But it does mean that finding enough resources to fulfill work is going to be one of the biggest challenges over the next few years for agencies and in-house brands.

One thing is certain, employment in the SEO industry is very strong right now.

How To Become A Network Security Engineer? A Simplified Guide

The following article includes a simplified guide on how to become a network security engineer

There is an ever-increasing demand for professionals in network security. According to the IT security non-profit ISC2, there is currently a workforce gap in the cybersecurity field of nearly 4.1 million workers, which would necessitate a 145 percent increase in the number of professionals (2.8 million) currently employed. Governments and businesses working to safeguard data assets face significant security risks as a result, and this highlights the need for increased cybersecurity professional education.

What are the Duties of a Network Security Engineer?

Accused of keeping up with the respectability of an association’s information, an organization security engineer consistently screens the organization for security breaks, completes mimicked assaults to recognize weaknesses, and creates security conventions to frustrate likely dangers. A network protection engineer manages infections, phishing assaults, spyware, deceptions, and other normal weaknesses.

Skills related to data security, such as installing firewalls and data encryption programs that safeguard sensitive information, are beneficial for those interested in becoming network security engineers.

Steps to Become a Network Security Engineer

Hopeful innovation experts can seek after an organization’s security engineer profession by making the accompanying strides.

Step 1: Complete a Bachelor’s Degree:

Most situations in network security expect a four-year college education, ideally in a PC-related field, like software engineering or programming. For instance, graduates of management information system (MIS) programs have the opportunity to acquire knowledge about cutting-edge technologies and other topics that will help them succeed as network security engineers. A designated degree program, like web-based unhitched males in online protection, gives an immediate establishment in network security profession preparation.

Careers in network security can also be made possible with degrees from other fields. For instance, students can learn about the differences between public, private, and nonprofit businesses and organizations by enrolling in online business administration programs. Graduates may be able to apply their general knowledge to more specialized fields thanks to the foundational business knowledge they acquire. In addition, gaining an understanding of the various organizational structures can lead to a deeper comprehension of the various types of data generated by each structure and the differences in data protection requirements.

Step 2: Achieve a Master’s Degree:

Master’s degrees may be preferred by some employers because they can better prepare graduates for leadership positions. For example, graduates of an online master’s program in software development can build adaptable abilities that can be used in a range of job routes. The skills covered include enhancing and developing programming abilities; mastering cloud and database environments; and developing user-friendly interface designs. The educational program is colossal and exceptionally particular.

Step 3: Obtain Work-Based Experience:

Past schooling, hands-on experience, and the drive to propel one’s range of abilities go quite far toward catching everyone’s eye. One method for acquiring traction as an organization security engineer is to become conversant in related PC fields, for example, information systems administration and programming dialects.

Obtaining certification in network security skills, such as the Certified Information Systems Security Professional,

Taking the initiative to remain up to date on trends affecting large amounts of data, and

The qualities and abilities that are most suitable for careers in network security are: Technical network security engineer skills include the following:

Problem-solving abilities for swiftly identifying and resolving network flaws

Analytical skills for carefully examining computer systems and networks and identifying vulnerabilities

Detail-oriented approach avoids sneaky cyberattacks

Resourcefulness or ingenuity for anticipating security risks and implementing new ways to neutralize them

Problem-solving abilities for training coworkers and leaders on threats and protection protocols

Ability to test for, track, and detect threats

Infrastructure documentation and event reporting capabilities

Knowledge of cyber laws and compliance

The U.S. Department of Work Measurements projects a 32% development rate in network security designing vocations from 2023 to 2028. development in the field is driven by a more prominent comprehension of the significance of information security amid a consistent ascent in assaults, including enormous scope information breaks, portable malware assaults, and ransomware dangers to foundations going from regions to wellbeing associations.

Concerning pay, the field of organization security by and large rewards insight with a more significant salary. The following sliding pay scale for network security engineers has been confirmed by PayScale:

Work experience of one to four years: US$74,000

Experience ranging from five to nine years: US$88,000

Experience ranging from 10 to 19 years: US$103,000

Over 20 years of involvement: US$114,000 Obtaining education and training in network security may also open doors to higher-paying positions in the field, such as chief information security officer and lead software security engineer.

How Does Malware Get Past Security Software?

Malicious software, or malware, is any software that causes damage to a computer system. Malware can take the shape of worms, viruses, trojans, spyware, adware, and rootkits, among other things, and can steal confidential information, erase documents, or install software that has operating system’s design and applications (such as older versions of Microsoft Internet Explorer supported by Windows XP) and susceptible versions of browser plugins. Even installing new versions of such plugins store data in a specific memory region fails to prevent more data from being supplied than the buffer can handle.

Malware may send data that overflows the buffer and includes harmful executable code or data at the end. When this payload is retrieved, it performs whatever the attacker, not the legitimate software, wants. Anti-malware software is becoming more dangerous to malware detection.

User Mistakes or Insecure Design

Floppy discs were used to start early PCs. When built-in hard drives became popular, the operating system was typically started from them, but it was possible to boot from a floppy disc, CD-ROM, DVD-ROM, USB flash drive, or network if one was available. When one of these devices was accessible, setting the computer to boot from it was typical. Usually, none would be available; instead, the user would purposefully place a CD into the optical drive, for example, to boot the computer in a unique method, such as to install an operating system. Computers can be programmed to run software on specific media when it becomes accessible, even if they are not booted.

The user would be tricked into booting or operating from an infected device or medium by malware distributors. A virus, for example, may make any USB stick inserted into an infected computer add auto-runnable code. Anyone who then connected the stick to a computer set to autorun from USB became infected and spread the infection in the same way.

Same OS Used Again

Suppose all computers in a network run the same operating system, for Windows and Mac OS X, in particular, have such a significant market share that an exploited vulnerability focusing on either operating system might compromise a significant number of systems. In the short term, introducing diversity just for the sake of robustness, such as adding Linux systems, may increase training and maintenance costs.

Signature Change

Viruses that change their signature can sneak past signature-based virus scanners. This is known as polymorphic malware, and it works by that has no effect on the virus’s functionality is enough to alter the signature and prevent antivirus software from recognizing it. The malware has an encryption generator, which generates various encryption techniques. The various encryption operations then encrypt and decrypt additional functions — the ones that damage the code and effectively tamper it.

New Method to Bypass Antivirus

The preceding approaches rely on obtaining a file onto the target machine and then executing it. There’s a newer technique of operating malware on a computer that doesn’t require anything to be saved on the target computer.

This sort of malware runs entirely in the memory of the computer, obviating the need for antivirus software. The malware is not sent directly from the infected webpage. Instead, it directs the machine to download the malware to a memory location by exploiting a previously known weakness in a related program. The memory region is then executed, just like the other malware variants.
