Types of Computer Security

There are several types of computer security. The most basic are Anti-virus, HSMs, Parental controls, and Firewalls. To learn more, read on. This article will discuss these types in more detail. If you’re looking for ways to secure your computer, read on to learn more. After reading this article, you’ll be well on your way to secure your machine. Let’s get started. Here are some examples of these security systems.

Anti-virus

The most basic form of computer security is antivirus software, but there are many other forms of protection available. Aside from running on individual computers, other forms of computer security include firewalls and Unified Threat Management. Some anti-virus software uses a heuristic approach, looking for files with characteristics that are similar to known malware.

Increasingly sophisticated artificial intelligence and machine learning technologies help antivirus software recognize new threats and improve their detection rates.

HSMs

Hardware security modules (HSMs) are a new class of device that provide key management, authentication and digital signing capabilities. In addition to providing encryption and authentication capabilities, HSMs also provide control and data encryption. Some HSMs are built-in and others are external devices. The differences between HSMs and TPMs include their cost, functionality and availability. TPMs provide general built-in processing environments, while HSMs specialize in cryptographic operations and secret key management.

Parental controls

If you have children and want to ensure they use the internet safely, you should install parental controls on their devices. These allow you to monitor their online activity and block specific websites or apps. You can also alter their settings to reflect their age and skills. Keep it Real online is a campaign that encourages parents to use parental controls on their children’s devices. However, if you don’t want to monitor everything your children do online, you can turn to parental … Continue reading >>>

Examples of Computer Security

There are several types of computer security, but a good example is physical security. There are also different types of protection, such as firewalls, input validation, and parameter tampering.

Despite these differences, physical security is still the most common form of protection. Listed below are examples of computer security:

Physical security

It’s important for every organization to have a comprehensive cybersecurity strategy, and physical security is just as important. Often overlooked, human factors associated with physical security are the biggest threat, and organizations need to develop comprehensive operational procedures to protect data and personnel. By integrating physical security into your physical security plan, you will ensure that your company’s data and assets remain safe and secure.

Listed below are some ways to improve the security of your company.

Firewalls

Firewalls are used to protect your computer from unwanted access. These programs analyze the data packets that are passed through them and look for malicious code. Once identified, the program can either drop the data packet or block it completely. Both methods are highly effective for preventing unauthorized use of your computer. If your computer has a password, make sure it is secret. Hardware authentication devices are also effective ways to secure your computer against unauthorized users. Otherwise, unauthorized users can abuse your computer in any way they see fit.

Input validation

Input validation protects a computer from being attacked by unauthorized users. It can be as simple as a word or a string of characters, or as complex as a database. Safe input validation techniques prevent attackers from using such unsafe data. However, some inputs cannot be properly validated, resulting in a security issue. One such type of attack is a buffer overflow, which causes a computer to stop responding or store too much data. This type of attack can … Continue reading >>>

Computer Security Concepts

The following article discusses computer security concepts, from Network security to Secure coding. You’ll also learn about Backdoors and Secure coding. To understand why these concepts are important to computer security, you should be familiar with them. However, if you’re unsure about them, read on! This article covers some of the key concepts of computer security. So, what do you really need to know? Keep reading to learn more about the latest computer security techniques.

Network security

A fundamental level of computer security is protecting a network from malicious software and unauthorized access. Network security is often performed by securing the network from external peripherals such as routers and bio-metric systems. These security systems ensure that unauthorized people cannot access network resources. They also protect data within the network, which is an important element of overall computer security. Listed below are some of the most important concepts in network security.

Secure coding

Understanding secure coding is essential for software development teams. Without secure coding, unauthorized users can exploit security flaws in software to gain control of the system. Understanding how to code securely will allow development teams to establish the right standards and make the appropriate security choices. Here are some tips to ensure the security of your software development projects:

Encryption

Encryption is a key component of any computer security system. Data shared over the internet travels across various network devices around the world, including the public internet. Because this information can be accessed by hackers, encryption is an important security feature to have in place. In addition to encryption, a user can also install software and hardware to protect data on a network. Here, we will discuss how encryption works. Once your data is encrypted, it is almost impossible for hackers to access it.

Backdoors

Backdoors in computer … Continue reading >>>

Computer Surveillance For Spyware Removal

Computer surveillance, also known as computer infiltration, is the act of spying on a computer system without the knowledge of the user. The spying may be done through the internet, through email or chat programs, or even when the computer is turned on and booting up. The ultimate goal of this activity is to gather data that can be later used in identity theft. In other words, it aims to steal your identity!

To understand how computer surveillance works, it’s necessary to have an understanding of how computers work and why they are important to have. A computer has two parts – the input and the output. It acts as a sort of computer system bus that sends and receives information from external sources. Some cables connect various computer systems.

Input:

This refers to the information that the computer system requires to function. It could be anything from user input such as keyboard strokes, mouse movements, images, and videos, etc., to software applications and device drivers. Output: This refers to the information the computer needs to process the input information. This could include stored data, received data, etc.

A computer surveillance system is used to gather information from a computer system without the knowledge of the user. This information is sent wirelessly from the computer to a remote site where it is decoded and analyzed. The decoded information is then used for a variety of purposes including determining passwords, monitoring computer use, and conducting targeted Internet search and browsing. The system also enables the monitoring of email and instant messaging as well as recording and storing of chat and web-based conversations.

Spyware:

Spyware is a program developed to monitor and collect information from a computer. There are many types of spyware like web bugs were keylogger, snoop ware, malware, and … Continue reading >>>

Social Engineering Hacking Tactics and How to Prevent Them?

The Nigerian prince has been around for decades now. The scamming chain mail allegedly coming from Nigeria about a prince who’s asking for your help is legendary. It is one of the best examples of social engineering hacking in the history of the internet. Take a look at this link for more information about it.

Thousands, if not millions of people fell for the scam. If you don’t want to be a part of the statistics for this trick, you should learn from their ways. Or, if you’re not too good at learning, you can call the professionals who know exactly what needs to be done.

Blocking email addresses, going through detailed searches to find the source of the scam, and other methods are being used. However, the best thing is to know if something like this is happening and not fall for them.

There are four stages of social engineering hacking

Every scam on the internet that is a part of social engineering has four main stages. Those are the identification of the victim, throwing bait to see if they are available, working to get the needed information, and getting a clean exit out of the situation. See this link for more information on social engineering: https://en.wikipedia.org/wiki/Social_engineering_(security).

Let’s look at them a little more thoroughly and learn how to recognize them:

1. Identification

The hackers won’t go for anyone. They first go through their social media, browser information, etc. If they identify the victim as eligible for their scams, they’ll jump in and attack. If not, they’ll go for someone else. This is how they might use an email from someone that seems familiar to the victim.

2. Throwing a bait

Once they have got all the information, the attacker is going to come up with a plot … Continue reading >>>
