Types Of Attacks On A Computer System - 1546 Words

Different Types of Attacks on Computer Systems What is attack on a Computer Systems? Attack on a systems or network is defined on your network infrastructure. Attacker will first analyse network environment and collect information in order to take advantage of the existing open ports or vulnerabilities. It may include unauthorized access to company’s resources. Passive attack - In some cases, the purpose of attack is only to learn and get some information from your computer system and your computer system resources are not manipulated or disabled in any way, then it is called Passive attack. And it is hard to detect that someone is monitoring you because you will not see any changes in your system. Active attack - Active attack occurs where the attacker accesses and either alters, disables or destroys your information or data. Attack can be happened either from outside of the organization means Outside Attack or someone from within the company who is an insider that already has access to the network which is called Inside Attack. Some of the attacks will be attacks targeting the end-users like Phishing or Social Engineering, those are usually not directly called as network attacks. Methods of attacks These are the methods that can be used to make an attack on a computer system. Distributed attack - A distributed attack are very strategic attacks. It requires particular code such as a Trojan horse or back-door program, to a trusted software that so, with thatShow MoreRelatedTypes Of Attacks On Computer System3184 Words   |  13 PagesDifferent Types of Attacks on Computer System Introduction A PC attack may be characterized as activities coordinated against PC frameworks to disturb gear operations, change transforming control, or degenerate put away information.

Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks thatRead MoreE Mail Bombing Attacks Are Just As They Sound1517 Words   |  7 PagesE-mail bombing attacks are just as they sound. Sometimes referred to as email flooding, an attacker sets up an algorithm to send â€Å"a large amount of emails simply fill up the recipient s inbox† (Goutam 15). Such attacks are designed to crash personal computers and/or the servers they are running on, given the computer is in an office. Attacks are done in one of two ways, the attacker makes a virus that uses ot hers emails to target a specific email, or the attacker simply runs an algorithm off theirRead MoreThe Effect Of Computer Vandals1430 Words   |  6 PagesDeacreased Privacy 2 Types of Security Attacks 3 Definitions 3 Hacker Attacks 4 Ways to Prevent Security Attacks 5 Introduction SUMMARY: This report will cover some of the different types of viruses and people who create them (hackers).
