Details about Spotting Malware Infiltration Faster, Steps to be Taken
Malware is considered the short term for malicious software, defining viruses, trojans, worms, and other harmful computer programs. Hackers use those programs to inflict destruction and gain access to sensitive information.
According to Microsoft, “Malware is a catch-all term referring to any software designed to damage a single server, computer or computer network.”
In other words, the software is recognized as malware based on its deliberate use rather than a particular technology or technique used to build it.
With phishing email and spam being the primary vector by which malware infects computers, the best way to avoid offensive maneuvers is always to check that your email systems are locked down tight – and your users know how to spot danger.
As such, some of the tips are to recommend a combination of checking very carefully attached documents, restricting potentially dangerous user behavior, and training the users about common phishing scams so that their common sense can kick in.
There are many steps a user can take, including keeping all the systems fixed and updated regarding more technical preventive measures. These measures include performing continuous vulnerability assessments on your infrastructure, and maintaining a checklist of hardware, so users can have an idea of what they need to protect their servers.
One way to be prepared regarding ransomware attacks is always to back up the user’s files by making sure they will never need to pay a ransom to get them back if the hard drive is encrypted.
Types of malwares
There are several different ways of categorizing malware; the first is knowing how malicious software spreads. Users may have heard the words Trojan, virus, and worm used; however, according to Symantec, we have three subtly different ways malware infect target computers:
-A worm is regarded as an autonomous piece of malicious software, reproducing itself and spreading from computer to computer.
-A virus means a piece of computer code that installs itself within the principle of a different standalone program. Then, it intensifies the program in order to take hostile action and spread itself.
-A Trojan is considered a program that cannot reproduce itself but poses as something the user needs while tricking them into activating it so it can do its damage and spread.
Malware Protection
Antivirus software is the most general merchandise regarding malware protection products. At the same time, high-end security pros regard it as out of date; it’s still the backbone of primary anti-malware defense.
The best antivirus software comes from vendors Symantec, Trend Micro, and Kaspersky Lab, according to recent tests by AV-TEST.
In order to talk more about advanced corporate networks, endpoint security offerings provide defense in depth against malware, in addition to giving the signature-based malware detection that the user expects from antivirus, personal firewall, anti-spyware, application control, and other styles of host intrusion prevention, in addition to checking what Security Measures are Taken in the Telecoms Industry.
How to detect malware
Even though users will try their best to stop the attacks, it’s still possible for the system to be infected by malware at some point.
People can use advanced visibility tools to see what’s going on in their networks and detect malware infections in the IT world. The majority of malware use the web to either send or spread information to their controllers, so network traffic includes signals of malware infection that users might otherwise miss.
It is worth mentioning that there are many network monitoring tools with prices ranging from a few dollars to a few thousand.
Also, we have the Security Information and Event Management (SIEM) tools, which evolved from log management programs; and analyze logs from appliances and computers across the infrastructure looking for signs of problems, including malware infection.
How to stop malware
Last but not least, malware attack prevention is a very controversial issue, while methods can vary depending on the type the user is dealing with.
Twenty-eight percent of data breaches involve malware, which threatens every organization and is becoming more common every day, according to Verizon’s 2019 Data Breach Report.
The best practices for how to stop malware attacks include:
-Employees should be trained to increase their IT security awareness and not fall for spam emails, phishing emails, and other social engineering attacks.
-Don’t give regular users administrative rights on their workstations.
-Perform a regular scan of the workstation and servers to spot outdated tools. Keep your antivirus software, digital vaccines, endpoint protection, and other security software and databases updated.
-The users should use the latest repairs to the operating systems and applications as soon as possible to reduce the length of time known vulnerabilities can be exploited. In parallel, testing new updates is very important, patches and hotfixes in a lab before applying them in production.
-Block known ransomware extensions via File Server Resource Manager. If ransom malware cannot create files with those extensions on your file server, it cannot encrypt your files.
The digital world is becoming more vulnerable and exposed to attacks and digital assaults that can be very hurtful and have severe consequences on users and people in general.

When it comes to ensuring the highest levels of cybersecurity for any establishment, password management in network security is one of the most paramount factors in guaranteeing security. As one of the essential cybersecurity measures, password management is a critical element for any online activity, whether for software or hardware. Everything is protected with a password.
What is Password Manager and How does it Work?
To those not familiar with the concept, password management’s significance exceeds the creation of a strong password to protect your data or account. It is a cybersecurity system. A system that manages any saved login credentials, all while guaranteeing a safeguarded relocation of data from one device to another. When coming up with a valid password, a few factors must be taken into account, such as the potential of being exposed to high risks and identity theft.
For any establishment, the correct password manager helps to monitor any activity and amounts of logins for servers people work on. As a software application, it is developed for storing and managing online credentials. With the increased available platforms and programs requiring safety credentials, the risk of losing or forgetting a password has never been higher. User password management, such as Google password manager, helps users with a handful of passwords for essential web applications.
By providing the needed digital space to generate and store any, and all passwords in one location, password management in network security keeps any data safe and secure in various ways, including biometrics data.
Why Use Password Manager?
Through the encryption of users’ logins, a reliable password manager protects your credentials and cannot be accessed until the master password is submitted. In this case, no password is stored on the device itself or even on the manager’s servers. While some might think that storing all of your important passwords in one place might be hazardous, the truth is, password managers are the safest bet to safeguard all your passwords, as the chances of a password manager being breached are extremely low and almost very unlikely to happen.
Without getting into all the technical terms as to why password managers are the safest option, these applications can be perceived as the lesser evil. While users will still need to create one master password – preferably to be long and a bit complicated – it will guarantee the protection of any login credential for any account or credit card information.
The ideal password managers to download are backed by two-factor authenticators, where users are asked for a one-time code alongside the password whenever a new login into a new device takes place.
Password Management Best Practices in Network Security
In terms of obtaining the highest level of protection for network security, few practices are applicable to almost anyone to ensure the highest level of user password management.
1. Training
Training the team and raising awareness of potential password threats is one of the most important things to consider. Team members working on network security have to understand the risk of cybersecurity and the importance of implementing the right measure to protect and secure any account credential.
2. Enforcement of Reliable and Strong Passwords
Enforcing the creation of strong passwords and establishing they follow the best practices for network security to protect the network and its data while respecting the integrity, confidentiality, and accessibility of the network’s computer systems.
This includes performing a thorough network audit, deploying network and security devices, disabling file sharing features, updating antivirus and anti-malware software, securing all routers, using a private IP address, and finally establishing a network security maintenance system.
3. Multi-factor Authentication
Endorsing your password management with two-factor authentication is like adding another solid layer of protection to your accounts and their passwords. Multi-factor authentication ensures that only people responsible for the network have access to its sensitive data.

We are all well aware of the troubles opening a fishy link can lead us to. Luring users to click on a given link has been of one the well-known techniques to get access to the device, install virus and malware or even go as far as creating a full ransomware attack. To protect your computer and private information, there are multiple techniques to check links without opening them. What is important though is never to open the link if it is suspicious.
Visually Inspect the Link
When you are not dealing with a shortened URL, the best way to go thoroughly through the link to see if there is any spelling mistake. Attackers usually tend to change a minimum number of letters so that you are unable to tell the difference. For instance, things like www.goagle.com instead of www.google.com should catch your attention with the second ‘o’ of Google replaced with an ‘a’.
Verify that Links in an Email Come from a Credible Source
Emails are the best sources for phishing attacks. These kinds of attacks are used to steal some sensitive information such as passwords and credit card information. The best way to avoid these kinds of attacks is to authenticate the sender. For that purpose, do not only check the name of the sender, you need to double-check the email the sender is using. In general, attackers use credible sender names with emails which do not correspond to the promoted identity. Next time you get an email from your bank like “XBank”, check that the sender email is person@Xbank.com rather than person@anyothermailclient.com.
Use Link Checker or Link Scanner
Many websites actually provide link checking or link scanning features. This is a very neat technique to simple check the link before clicking on it.
VirusTotal
www.virustotal.com is an excellent website for this task. This online tool practically does the job of an anti-virus. When you go to the website, you have the possibility to analyze files and URL for malware or any other security breach. Once you submit your file or enter the URL, the website will use different tools and software, then provide you with a detailed output from each of these tools. If you are unsure if a given software is credible enough, you can compare it to the output of other platforms on a single website.
Use a Short URL Expander
Sometimes attackers try to shorten URLs to hide any malicious intention. Analyzing shortened URL is not straightforward. To overcome this problem, copy the provided URL without opening it and use specific websites that actually expand the provided URLs. Then, you can analyze the original URL for possible security breaches. Many websites are there to do this task. Just search for “short URL expander” on your search engine and use the top provided websites.
Upgrade your Anti-Virus with Internet Security Features
Anti-virus software is commonly used to protect personal computers from viruses and other malware. While these are available for free, you can easily upgrade them to include internet security features for a small monthly fee. This will bring major improvement to your internet browsing experience including custom-made safe browsing tools.
Use Google Transparency Report
Google provide a nice tool to check for the safety of websites. To do so, visit https://transparencyreport.google.com and enter the URL in question. The Google source will then provide you with a safety report of that website.
Simply Hover Over the Link
The nicest solution is kept to the end. When you hover over a link in your email client or web browser, a small square appears including all the information related to the chosen URL. These details can be used to give a preliminary indication whether to trust the source.
Final Thoughts
Suspicious links are everywhere! To make sure they don’t catch you by surprise, follow the highlighted and you’ll be safe to go.

Cybersecurity and artificial intelligence (AI) are two very trending topics at the moment. AI has been the pivotal elements modifying business strategies, improving decision-making processes, and triggering automation in every industry in the world. The latest sentience debate is a clear indicator on serious and advanced AI is becoming nowadays. Cybersecurity is the other important element of today’s technological world. With an increasing reliance on data and the move to online services that require an individual’s biometrics, security essential in preventing data thefts and associated cybercrimes. AI has undeniably improved cybersecurity practices by allowing a real-time analysis of internet traffic to discover possible threats at the earliest and take defensive actions. This important learning process hides however several disadvantages of AI in cybersecurity.
What Are the Downsides to AI in Cybersecurity?
The touted advantages of AI in cybersecurity are real and very useful. However, the increasing adoption of AI solutions for security is actually causing problems at different levels.
Hackers Use AI as Well
When it comes to maturity in technology, hackers are the best at it. These individuals sitting behind computer screens logging data and doing advanced analytics to identify any loophole or vulnerability they can use to their benefits. The use of AI as far as cybersecurity is concerned is a double-edged sword. It is actually a race of who can develop a better algorithm that caters better to the data which is circulating online. In this sense, the use of AI is a big threat to security.
Another issue is that while a company is analyzing and learning from data to discover threats, a hacker is concurrently analyzing the company’s cyber-defense mechanisms and policies to find “open doors’ that will take it into the system to complete the intended attack.
Data Confidentiality
AI algorithms are associated with the analysis with large volumes of data, a key requirement for the developed algorithms to produce accurate outputs. The data a company deals with contains normal traffic related to daily transactions and activities, but also sensitive information related to the clients including their biometrics and personal information. What happens to our data when it goes to the AI-agent though is another thing. Protecting the data is key when AI is used for cybersecurity reasons. The secrecy of the clients’ data should not be compromised for any reason.
Increasing Need for Data
The field of cybersecurity is constantly evolving with ingenious attacks and threats emerging every now and then. Browser-in-the-browser attacks and increasingly advanced ransomware attacks have been notable examples in 2022. In order to discover attacks at a later stage, the AI algorithm needs to have data to do the proper training. The increasingly dynamic environment with threats emerging and evolving will lead to a surge in the required volumes of data, which can potentially not be readily available to have a fast response to the attack itself. Whether it is the ability of AI to keep track of the exponential growth in data or the availability of data for the AI-algorithm to produce results is a big disadvantage of this approach for cybersecurity
Will Cybersecurity be Replaced by AI?
With the drive towards more and more automation, it is questionable whether this can be applied as well for cybersecurity practices. AI can certainly assist in processing and learning from data and produce insights. However, the real decision maker in such as sensitive area where no errors can be tolerated is the cybersecurity expert himself. The only way for AI to replace cybersecurity is when it becomes sentient or developed enough to think and act like humans do. There is still a long way for that to concretize.
Explainable or interpretable AI is a key intermediate step in reaching this target. First, we need to understand how AI produces results. Proper cybersecurity practices require a reduction in bias while optimizing the performance of the algorithm.
How Will AI Affect Cybersecurity Jobs?
The adoption of AI will certainly cause major shifts in the cybersecurity job market as in the case in other industries, but probably at a smaller scale. The level of skill and experience needed to thwart cyberattacks will safeguard the need for security experts to provide the final decision regarding suspicious data patterns.
On the other hand, the incorporation of AI will call for new skilled workers that can manage and optimize the performance of the algorithms. Another alternative would be for existing workforce to be upskilled and retrained to handle the new analysis tools.
Summary
As data is becoming the basic unit for decision making, AI has invaded all industries and businesses, including cybersecurity. Companies are starting to incorporate learning algorithms to their offered services in order to have a more intelligent management of the different security threats. However, the role of AI in cybersecurity should be considered with enough judgment. The addition of AI would increase the complexity in the data management process, notably in terms of data privacy and the continuous need for more data.
