How To Protect Your Computer From Malicious Activities

computer security fundamentals

Without these fundamental protocols, your entire system is prone to hacking, downtime and security breaches. It’s imperative to learn these computer basics as soon as possible. This will give you the upper hand in limiting the damage hackers can do to your system.

The first of the computer system security fundamentals is authentication. Everyone knows the basics: use passwords to protect our systems from unauthorized entry, use software passwords to protect software settings and user id on files and folders, and use smart card readers for access control. However, these basic security practices aren’t enough. We also need to use smart cards or biometrics to further protect our computers. This second layer of security not only offers a more foolproof way to keep hackers away, but also makes our computers safer against malware and spyware that might infiltrate our computers when they aren’t being used.

Identity Protection

Identity protection is the next computer security fundamental that must be taught. Hackers target companies and businesses that provide us with personal information. Whether it’s our social security numbers, credit card numbers, bank account numbers, or passwords, these hackers have the potential to ruin the operation of our business and cause massive monetary damage. Personal safety is absolutely essential in any business environment, and we should never take chances when it comes to the safety of our company’s and the individual employee’s data.

Another aspect of computer security is ensuring that we all update our virus, spam and spyware detection and removal software regularly. In fact, most experts recommend that we install and run anti-virus, anti-spam and anti-spyware scans on a regular basis, to ensure that our computer systems are protected from malicious intrusions. Some of the most common threats to computer networks come from Trojan horses, worms, phishing emails and malicious websites. All of these malicious programs are designed to expose personal information and cause instability or otherwise harm to a computer system. If we have scanned our computer systems recently, we can detect these attacks and stop them before they compromise our important data.

Network Firewalls

Network firewalls protect computers from unauthorized access. These are installed between network interfaces and firewall messages are delivered to the user interface, warning that an internal system is infected. There are several different types of network firewalls, including IP-based firewalls, which prevent connections to certain areas of the Internet. For companies that don’t want to install a router, a built-in firewall is sufficient to protect most computer systems.

Antivirus is another computer security feature that prevents viruses from installing themselves into our computer systems. However, as mentioned earlier, not all viruses are detected by anti-virus programs. If a virus is able to bypass security, it could potentially harm your computer. The best way to protect yourself is by having an updated antivirus package. It’s recommended to have a complete scan on your computer once a week. You can also run daily full virus scans to detect any changes to the computer system.

Final Words

Trojans and worms are capable of damaging computer systems. Firewalls prevent intrusion attempts and prevent viruses and other malicious software from entering a computer system. We can also safeguard our computers against intrusions using antispyware and antivirus. There are different types of anti-spyware and anti-virus packages available on the market today. We can choose a good one to protect our computer systems. Computer security is an issue that must be addressed for maintaining the computer systems and protecting our personal information. Prevention is better than cure. Install an antivirus and firewall program on the computer system to protect it from possible intrusions and unauthorized transactions
