Security software are the need of the hour. There are several types of such software available in the market that you can use to guard your computer against different types of attacks that can damage your data.
Some of the most common types of security systems are explained below in detail. The best practice is to use a mixture of multiple software so that you stay guarded at all times
A firewall, as the name suggests, stands like a wall that blocks unauthorized access. Many operating systems, such as Microsoft Windows XP, come with built-in firewalls that should be properly enabled to provide protection.
A very famous form of firewall is ‘Application Firewall’ that controls access (input and output) to or from service or application. It blocks access to those requests that do not meet the firewall’s configured policy. The two main types of application firewall are (1) network based (2) host based
The main aim of both the types is so stop intrusion and keep the data safe.
It is very important for every computer to have antivirus so that it remains guarded against viruses that can cause computers a huge amount of damage. Many big corporations including Avast!, AVG Technologies, McAfee, Avira and Microsoft are producers of antivirus software.
Their main duty is to stop malicious codes from attacking a computer. They are equipped to identify such codes and prevent them from causing damage. They are also designed to repair damage by removing the virus if it has found its way into a computer.
It is important to use a trusted antivirus that guards against all types of attacks. Additionally, they should be updated regularly so that one stays protected against all types of viruses.
Just like antivirus software, the main purpose of antispyware is also to guard computers. However, the main difference is the way they do so. Antivirus software guards computers against attacks. In comparison, antispyware software stops unauthorized software from transmitting information from the user’s computer to unauthorized sources.
Generally, antivirus software are not able to guard against such attacks because spyware do not attack any file, hence they do not get prevented by antivirus software. However, antivirus software may be able to detect them when they send messages or information to external recipients. Conversely, they may not be able to stop them from doing so, which is why there is the need to have antispyware software.
Single sign-on is software that gives a user access to all the systems by logging in once. This removes the need of the user having to log in again and again to access a system. The same technique is used when the user signs out.
This system greatly reduces password fatigue by removing the need for multiple logins. Additionally, it also greatly helps save time. However, it is often criticized as it puts the system at risk as one single password gives access to all the files. If the login information reaches unsafe hands, the person may enter all the systems and cause damage, hence it is considered unsafe by many. If this system is being used, one should make sure that the password is tough to crack and doesn’t reach unsafe hands.
Some security software individually protect desktops. Also known as end-point software, these types of software exclusively operate on the desktop. However, this type of applications often causes the computer to slowdown as it uses system resources. Yet, it provides strong protection as it is operated in real time.
These types of software work on a network as opposed to desktop software which only guard individual desktops. These applications filter the data that is transmitted over the network such as routers and gateways. They stop files that may cause damage from being transmitted so that viruses do not spread throughout the network. These types of software are generally run on dedicated systems or servers and do not use the resources of end user desktops.
