Computer security software or cybersecurity software is any computer program designed to enhance information security. Security software is a broad term that encompasses a suite of different types of software that deliver data and computer and network security in various forms.
Security software can protect a computer from viruses, malware, unauthorized users and other security exploits originating from the Internet. Different types of security software include anti-virus software, firewall software, network security software, Internet security software, malware/spamware removal and protection software, cryptographic software, and more.
In end-user computing environments, anti-spam and anti-virus security software is the most common type of software used, whereas enterprise users add a firewall and intrusion detection system on top of it.
Security soft may be focused on preventing attacks from reaching their target, on limiting the damage attacks can cause if they reach their target and on tracking the damage that has been caused so that it can be repaired. As the nature of malicious code evolves, security software also evolves.
Firewall. Firewall security software prevents unauthorized users from accessing a computer or network without restricting those who are authorized. Firewalls can be implemented with hardware or software. Some computer operating systems include software firewalls in the operating system itself. For example, Microsoft Windows has a built-in firewall. Routers and servers can include firewalls. There are also dedicated hardware firewalls that have no other function other than protecting a network from unauthorized access.
Antivirus. Antivirus solutions work to prevent malicious code from attacking a computer by recognizing the attack before it begins. But it is also designed to stop an attack in progress that could not be prevented, and to repair damage done by the attack once the attack abates. Antivirus software is useful because it addresses security issues in cases where attacks have made it past a firewall. New computer viruses appear daily, so antivirus and security software must be continuously updated to remain effective.
Antispyware. While antivirus software is designed to prevent malicious software from attacking, the goal of antispyware software is to prevent unauthorized software from stealing information that is on a computer or being processed through the computer. Since spyware does not need to attempt to damage data files or the operating system, it does not trigger antivirus software into action. However, antispyware software can recognize the particular actions spyware is taking by monitoring the communications between a computer and external message recipients. When communications occur that the user has not authorized, antispyware can notify the user and block further communications.
Home Computers. Home computers and some small businesses usually implement security software at the desktop level - meaning on the PC itself. This category of computer security and protection, sometimes referred to as end-point security, remains resident, or continuously operating, on the desktop. Because the software is running, it uses system resources, and can slow the computer's performance. However, because it operates in real time, it can react rapidly to attacks and seek to shut them down when they occur.
Network Security. When several computers are all on the same network, it's more cost-effective to implement security at the network level. Antivirus software can be installed on a server and then loaded automatically to each desktop. However firewalls are usually installed on a server or purchased as an independent device that is inserted into the network where the Internet connection comes in. All of the computers inside the network communicate unimpeded, but any data going in or out of the network over the Internet is filtered trough the firewall.

F.A.Q. about Security Software
What is IT security software?
IT security software provides protection to businesses’ computer or network. It serves as a defense against unauthorized access and intrusion in such a system. It comes in various types, with many businesses and individuals already using some of them in one form or another.
With the emergence of more advanced technology, cybercriminals have also found more ways to get into the system of many organizations. Since more and more businesses are now relying their crucial operations on software products, the importance of security system software assurance must be taken seriously – now more than ever. Having reliable protection such as a security software programs is crucial to safeguard your computing environments and data.
It is not just the government or big corporations that become victims of cyber threats. In fact, small and medium-sized businesses have increasingly become targets of cybercrime over the past years.
What are the features of IT security software?
- Automatic updates. This ensures you don’t miss any update and your system is the most up-to-date version to respond to the constantly emerging new cyber threats.
- Real-time scanning. Dynamic scanning features make it easier to detect and infiltrate malicious entities promptly. Without this feature, you’ll risk not being able to prevent damage to your system before it happens.
- Auto-clean. A feature that rids itself of viruses even without the user manually removing it from its quarantine zone upon detection. Unless you want the option to review the malware, there is no reason to keep the malicious software on your computer which makes this feature essential.
- Multiple app protection. This feature ensures all your apps and services are protected, whether they’re in email, instant messenger, and internet browsers, among others.
- Application level security. This enables you to control access to the application on a per-user role or per-user basis to guarantee only the right individuals can enter the appropriate applications.
- Role-based menu. This displays menu options showing different users according to their roles for easier assigning of access and control.
- Row-level (multi-tenant) security. This gives you control over data access at a row-level for a single application. This means you can allow multiple users to access the same application but you can control the data they are authorized to view.
- Single sign-on. A session or user authentication process that allows users to access multiple related applications as long as they are authorized in a single session by only logging in their name and password in a single place.
- User privilege parameters. These are customizable features and security as per individual user or role that can be accessed in their profile throughout every application.
- Application activity auditing. Vital for IT departments to quickly view when a user logged in and off and which application they accessed. Developers can log end-user activity using their sign-on/signoff activities.
