Computer security systems are defined as the combinations of the preventive program in form of software to keep computer system safe from all illegal activities and data damaging malicious codes. Communication today is based on internet every where. People communicate through emails b sending and receiving the data in the for of digital packets. At the back end these packets can be seen by some unauthorized body and identity theft could take place which can teal you’re confidential data including credit card numbers, important account passwords
Requirements of computer security system
Computer security system are needed to prevent the data form being damaged and theft When working with the network. The need of computer security increase wit the wider networks .people send malicious codes and infection sin the forms of attractive news and computer settings that on clicking can damage the whole secondary storage of etc computer. Online business activity cannot be carried out effectively without sufficient computer security such as online transactions and E banking.
Major threat to the computer system
The major threats to the computer are the infections that can enter the computer system though data travelers that can damage disk when inserted in the USB slots.
- Lack of security knowledge sometime increase threat for the compute system when people interact with viruses unknowingly.
- Poor encryption and carelessness in using the internet.
Computer security softwares
Anti virus softwares
There are many techniques that can provide required security to the system. Most of the commonly use security software are the advanced antivirus applications that are capable of cleaning, detecting and maintaining the security matters for safety of computer system. At present famous antivirus programs are Nod32,Avira, Avast ,syemantic and Norton..
Other security technique involves data encryption software that encrypts the data. This technique is mostly use din the electronic mail services for sending and receiving messages. Typical security algorithms are used for this purpose that encrypts or hide the packets in some unknown that is only readable by the concerned protocol or IP addresses
Another way to provide security to the computer system is to make use of the data filtration softwares. These softwares are capable of detecting infected or suspicious data while downloading various applications and files fro the internet. These softwares work similar to the firewalls. Latest operating system also provides ready security setting and update sot provide the users with the initial data safety.
All antivirus and firewall program area recognized as encrypted type of computer security system. Computer security system must assure that computer and its files are safe, only firewall, and cannot provide bets computer security. To avail the best security package combination of these security measures should be used.
Private disks are the secondary storage device wit high security feature provided for the commercial use. Server data and confidential records are stored ion private disks that prevent the data leakage .these disks use advanced security algorithms. they have set a new trend in the computer security .One of the most fascinating feature of the private disks are that they not only encrypt the data on the disks but also scans the whole disk with internally configured proactive firewall which can be very helpful in scanning and tracing the infection in digital cameras, mobile phones, flash drives and memory cards. Some times they are known as on fly security devices.
Security systems never get old. The experience relevant and required modification with the increased data threats and advanced technology. At present private disk excelled in providing best data security system at low cost. It is known as strongest data security providers. in future advancements in the anti virus programs are also expected that can be beneficial for compute systems.
