Download Free PDF. Type of Security Threats and its Prevention. Download PDF. A short summary of this paper. New hacking techniques are used to penetrate in the network and the security vulnerabilities which are not often discovered create difficulty for the security professionals in order to catch hackers.

The difficulties of staying up to date with security issues within the realm of IT education are due to the lack of current information. The recent research is focused on bringing quality security training combined with rapidly changing technology. Online networking security is to provide a solid understanding of the main issues related to security in modern networked computer systems. This covers underlying concepts and foundations of computer security, basic knowledge about security-relevant decisions in designing IT infrastructures, techniques to secure complex systems and practical skills in managing a range of systems.

Computer security is the process of preventing and detecting unauthorized use of your computer. Prevention measures help you to stop unauthorized users from accessing any part of your computer system. Detection helps you to determine whether or not someone attempted to break into your system, if they were successful, and what they may have done.

Masters of disguise and manipulation, these threats constantly evolve to find new ways to annoy, steal and harm. Arm yourself with information and resources to safeguard against complex and growing computer security threats and stay safe online.

There are some common Threats to attack the system. Virus ThreatsThreat, a computer virus is a program written to alter the way a computer operates, without the permission or knowledge of the user. A virus replicates and executes itself, usually doing damage to your computer in the process B. Spyware Threats A serious computer security threat, spyware is any program that monitors your online activities or installs programs without your consent for profit or to capture personal information.

We've amassed a wealth of knowledge that will help you combat spyware threats and stay safe online. HackersPeople, not computers, create computer security threats and malware. Hackers are programmers who victimize others for their own gain by breaking into computer systems to steal, change or destroy information as a form of cyber-terrorism.

Internet Based Attacks While your computer is connected to the Internet it can be subject to attack through your network communications. Viral Web Sites: Users can be enticed, often by email messages, to visit web sites that contain viruses or Trojans.

These sites are known as viral web sites and are often made to look like well-known web sites and can have similar web addresses to the sites they are imitating. Users who visit these sites often inadvertently download and run a virus or Trojan and CA F. Spyware, Adware and Advertising Trojans Spyware, Adware and Advertising Trojans are often installed with other programs, usually without your knowledge.

They record your behaviors on the Internet, display targeted ads to you and can even download other malicious software on to your computer.

They are often included within programs that you can download free from the Internet or that are on CDs given away free by magazines. Spyware doesn't usually carry viruses but it can use your system resources and slow down your Internet connection with the display of ads. If the Spyware contains bugs faults it can make your computer unstable but the main concern is your privacy.

These programs record every step that you take on the Internet and forward it to an Ad Management Centre which reviews your searches and downloads to determine your shopping preferences. The Ad Management Centre will build up a detailed profile of you, without your knowledge, and can pass this on to third parties, again without your knowledge.

Some Spyware can download more serious threats on to your computer, such as Trojan Horses. Unsecured Wireless Access Points:If a wireless access point, e.

Bluesnarfing:The act of stealing personal data, specifically calendar and contact information, from a Bluetooth enabled device. Social EngineeringTricking computer users into revealing computer security or private information, e.

Viewing a Word document in a text editor can reveal the metadata in plain text at the start and finish of the document. PreventionIf you were to secure your house, prevention would be similar to placing dead bolt locks on your doors, locking your window, and perhaps installing a chain link fence around your yard. You are doing everything possible to keep the threat out.

DetectionYou want to be sure you detect when such failures happen. Once again using the house analogy, this would be similar to putting a burglar alarm and motion sensors in the house. These alarms go off when someone breaks in. If prevention fails, you want to be alerted to that as soon as possible.

ReactionDetecting the failure has little value if you do not have the ability to respond. What good does it to be alerted to a burglar if nothing is done? If someone breaks into your house and triggers the burglar alarm, one hopes that the local police force can quickly respond.

The same holds true for information security. Once you have detected a failure, you must execute an effective response to the incident. Related Papers.

In October a Task Force was organized by the Advanced Research Projects Agency now the Defense Advanced Research Projects Agency to study and recommend appropriate computer security safeguards that would protect classified information in multi-access, resource-sharing computer systems. A slightly modified version of the report — the only omissions were two memoranda of transmittal from the Task Force to the Chairman of the Defense Science Board and onward to the Secretary of Defense — was subsequently published as Rand Report R, Security Controls for Computer Systems. At that time it was felt that because representatives from government agencies participated in the work of the Task Force, the information in the report would appear to be of an official nature, suggestive of the policies and guidelines that would eventually be established.
