Computers help us maintain our financial, social and professional relationships. We use them for banking and bill payments, online shopping, connecting with our friends and family via email and social networking sites, searching for data posted on the Internet, and more. We rely heavily on our computers to provide these services, but we sometimes forget our need to secure them. Because our computers play a crucial role in our lives and we capture and visualize a large amount of personally identifiable information (PII), it is imperative to maintain computer security that ensures the secure processing and storage of our information.

What is PC Security?
PC Security refers to technologies used to secure PCs, laptops, and other personal devices on a network. Computer security concerns private and public computer networks. Any unauthorized and illegitimate access is prevented from infecting virtual information, equipment and services. Computer security is essential to avoid any modification or damage that may be caused by malicious threats. PC security is also called computer security or cyber security.
Computer security is essentially about protecting computer systems and information from damage, theft and unauthorized use. This is the process of preventing and detecting the unauthorized use of your computer system. People often confuse computer security with other related terms such as information security and cyber security. One way to check the similarities and differences between these terms is to ask for what is guaranteed. For example,
- Information security protects information against unauthorized access, modification, and deletion
- Security means securing an autonomous machine by keeping it up-to-date and corrected.
- Security is defined as the protection of computer systems, which communicate via computer networks.
PC security vulnablities
A backdoor in a computer system, cryptosystem, or algorithm is a secret method of circumventing normal authentication or security checks. They can exist for a number of reasons, including original design or misconfiguration. They may have been added by an authorized party to allow legitimate access, or by an attacker for malicious reasons; but whatever the motives for their existence, they create a vulnerability.
Denial of Service (DoS) attacks are designed to make a machine or network resource inaccessible to the intended users. Hackers may refuse service to individual victims, for example by deliberately introducing an incorrect password repeatedly enough for the victim’s account to be locked, or they may overload the capabilities of a machine or a network and block all users at the same time. Although a network attack from a single IP address can be blocked by adding a new firewall rule, many forms of Distributed Denial of Service (DDoS) attacks are possible, with the attack coming from a lot of points – and the defense being much more difficult.
An unauthorized user who physically accesses a computer is likely able to directly copy data from it. They can also compromise security by modifying the operating system, installing software worms, keyloggers, hidden listening devices, or using wireless mice. Even when the system is protected by standard security measures, these can be bypassed by booting another operating system or tool from a CD-ROM or other bootable media. Disk Encryption and the Trusted Platform Module are designed to prevent these attacks.
Clandestine eavesdropping involves surreptitiously listening to a private conversation, usually between hosts in a network. For example, programs such as Carnivore and Narus In Sight have been used by the FBI and the NSA to listen to ISP systems. Even machines operating as a closed system (that is, without contact with the outside world) can be listened to by monitoring the weak electromagnetic transmissions generated by the equipment; TEMPEST is a specification of the NSA that refers to these attacks.
Multi-vector, polymorphic attacks
Surfacing in 2019, a new class of multi-vector, polymorphic cyber threats surfaced that combined several types of attacks and changed form to avoid cyber security controls as they spread. These threats have been classified as fifth generation cyber attacks.
Phishing involves acquiring sensitive information such as usernames, passwords, and credit card information directly from users. Phishing is usually done by spoofing email or instant messaging. It often prompts users to enter information on a fake website that looks almost identical to the legitimate site. The fake website often requests personal information, such as login information and passwords. This information can then be used to access the actual account of the individual on the actual website. Preferring the trust of the victim, phishing can be classified as a form of social engineering.
Basic Components of PC Security Software
Our Security developers are working harder to provide PC security to home users and businesses with next generation and advanced technologies to overcome malware issues. Antivirus software, firewall and Internet security, cloud storage are the basic components of computer security which are included in RAM Antivirus software.
- Antivirus: Antivirus software is used to scan and detect any type of malicious program including viruses, worms, rootkits, keyloggers, ransomware, etc. Frequent updates and fixes to antivirus security issues are very important and should be made available to users to update them, even before the vulnerability affects the users’ system.
- Firewall: A firewall does not allow unauthorized access to the users’ system when they are connected to the network. Anything that goes out of the Internet, has to go through the firewall, is examined and if the messages are deemed unauthorized and do not comply with the security rules, they are immediately blocked.
- Internet Security Suite: An Internet security suite provides a multi-layered security approach that includes antivirus, firewall, anti-spyware, behavior analysis, virus scanning, scheduled scanning, and more. Enhanced versions of the Internet Security Suite implement heuristic-based protection and prevention.
- Cloud Storage: This helps secure user data and contributes to PC security. Data, when stored on your PC, takes up a lot of memory. To avoid this and to secure against malicious hackers, data can be stored in the cloud, managing a cloud storage account, and thus contributing to data security.
How to choose the best PC Security software
Keeping your PC secure is essential to protect the personal, professional and financial information it contains. Fortunately, it is easy to secure your computer if you take the proper precautions. The use of secure passwords and verification processes will make it more difficult for another person or program to emulate you and access your information. Using security software like RAM Internet Security will make it harder for a hacker, virus, or malware to enter your PC. In addition to protection programs, the use of encryption and secure practices will contribute to the security of your data when you use the Internet.
