Anti-Virus & End Point Protection
Endpoint protection is an approach to protect those computer networks which are remotely connected to client devices. With the workforce getting mobile, laptops, desktops, and other wireless devices are now being connected to different corporate networks. This has opened several paths for cyber-attack agents entering the corporate network and causing irreparable data loss. Endpoint protection can ensure that such wireless devices are following the compliance to standards for corporate network security.
Anti-virus and endpoint protection tools can help network administrators to restrict access to certain websites, which don’t comply with a company’s security standards. With an updated anti-virus software and virtual private network (VPN) client, organizations can limit the access of computer devices to virtual LAN.
Antivirus Software is designed to detect, block and remove malicious software (malware). It is needed to protect systems, networks, smartphones, tablets etc. against all kinds of malware. Businesses today need antivirus protection more than ever before. On the one hand, all corporate data is saved on computers these days while on the other hand sales and transactions are also carried out online now. Thus customers’ personal data is also processed online and also stored. In this situation, it becomes important that corporate data, as well as customers’ personal data, are protected from being stolen by hackers. Similarly, with computer technology and the internet having involved as key to almost every business today, antivirus protection becomes inevitable.
There are different kinds of viruses that are available which affect computers, devices and networks. These can be broadly classified as:-
Other types of viruses include email viruses (macro viruses that spread through emails), network viruses (which spread through local area networks and the internet), Trojan horse viruses (which try to cheat users appearing as a desirable virus, but which in actuality would be malicious) etc.
Running more than one anti-virus on the computer is not recommended unless specified specifically by the vendors. Anti-Virus product has some modules like real time scanning of files and real time scanning of mails, which seemingly integrates with OS to provide such services. Such integration can cause problems if there are multiple such services being installed and doing the same task. This way technical issue may arise as such modules are not designed with keeping such things in mind. Technical issues may cause your system to freeze repeatedly which may lead to data loss or unstable system etc.
With hundreds of new malware strains being created every day, antivirus software is, for many people, the primary means of protecting both themselves and their computers from an ever-growing range of threats.
Some antivirus has an ability to detect and neutralize malware. Here are a few key features along with a brief description of what antivirus do:-
Antivirus programs are powerful pieces of software that are essential on Windows computers. An antivirus program is an essential part of a multi-layered security strategy – even a smart computer user, the constant stream of vulnerabilities for browsers, plug-ins, and the Windows operating system itself make antivirus protection important. The Antivirus Software firstly checks the program, comparing it to known viruses, worms and other types of malware. Moreover, Antivirus software also does “heuristic” checking, checking programs for types of bad behaviour that may indicate a new and unknown virus. The steps may defined as:-
It is always good to uninstall existing virus protection software while installing a new one, because many antivirus programs, while being installed, won’t install if they detect existing antivirus software on the system.
In network security, endpoint security refers to a methodology of protecting the corporate network when accessed through remote devices such as laptops or other wireless and mobile devices. Each device with a remote connecting to the network creates a potential entry point for security threats.
Usually, endpoint security is a security system that consists of security software, located on a centrally managed and accessible server or gateway within the network, in addition to client software being installed on each of the endpoints (or devices). The server authenticates logins from the endpoints and also updates the device software when needed. While endpoint security software differs by vendor, most software offers to provide antivirus, antispyware, firewall and also a host intrusion prevention system.
Endpoint security management is a holistic approach to network security that requires endpoint devices to comply with specific criteria before they are granted access to network resources. The Endpoints devices can include PCs, laptops, smart phones, tablets and specialized equipment such as bar-code readers or point of sale (POS) terminals.
Endpoint security management systems, which can be purchased as software or as a dedicated appliance, discover, manage and control computing devices that request access to the corporate network. Required elements may include an approved operating system, a VPN client and anti-virus software with current updates. Devices that do not comply with policy are given limited access or quarantined on a virtual LAN (VLAN).
Endpoint security systems work on a client/server model in which a centrally managed server or gateway hosts the security program and an accompanying client program is installed on each network device. In a software-as-a-service (SaaS) delivery model, the host server and its security programs are maintained remotely by the vendor. In either delivery model, when a client attempts to log onto the network, the server program validates user credentials and scans the device to make sure that it complies with defined corporate security policies before allowing access to the network.
Endpoint security is a strategy in which security software is distributed to end-user devices but centrally managed. Endpoint security systems work on a client/server model. A client program is installed on or downloaded to every endpoint, which, in this case, is every user device that connects to the corporate network. Endpoints can include PCs, laptops, handhelds, and specialized equipment such as inventory scanners and point-of-sale terminals. A server or gateway hosts the centralized security program, which verifies logins and sends updates and patch.
Antivirus software is a computer program that detects, prevents, and takes action to disarm or remove malicious software programs, such as viruses and worms. It helps in protect the computer against viruses by using antivirus software, such as Microsoft Security Essentials, Avast Anti-Virus. Computer viruses are software programs that are deliberately designed to interfere with computer operation; record, corrupt, or delete data; or spread themselves to other computers and throughout the Internet. There is a regular need to automatic updates of anti-virus software to prevent the most current viruses enter to the systems.
The Endpoint Security system works on a client-server model. Within the network there would be the security software, located on a centrally managed and accessible server or gateway. On each endpoint or endpoint device would be located the client software. The security software authenticates logins made from the endpoints and simultaneously updates client software when needed.
Endpoint Security also works as a SaaS (Software-as-a-Service) model; here the security programs and the host server are both maintained remotely by the merchant.
