Types Of Computer Security Threats 9. Social Engineering Social engineering is a non-technical method of intrusion hackers use that relies heavily on human interaction and often involves tricking people into breaking normal security procedures.

Reverse Social EngineeringAttack In this kind of cyberattack, the attacker convinces a user that they have a problem and that the attacker has a solution to the problem. Virus Virus is a program that replicates. It spreads from file to file on your system infecting them. Trojan Trojan horses pose as useful software, such as a legitimate program. Instead of being well-behaved software, aTrojan opens a backdoor on your system.

Spyware A common computer security threat, spyware is a class of malicious program that secretly steals your personal information and sends it to advertisers or hackers. Rootkit A rootkit is a program or a collection of programs that in itself is not harmful, but helps viruses and malware hide from antivirus software. Top Computer Security Actions Top Computer Security Actions 1. Patch, Patch, Patch! Set up your computer for automatic software and operating system updates.

An unpatched machine is more likely to have software vulnerabilities that can be exploited. Install Security Software When installed, the software should be set to scan your files and update your virus definitions on a regular basis. Choose Strong Passwords Choose strong passwords with letters, numbers, and special characters to create a mental image or an acronym that is easy for you to remember. Create a different password for each important account, and change passwords regularly.

Top Computer Security Actions 4. Backup, Backup, Backup! This may cause some operating systems such as Windows to crash or lock up.

Once authentication is complete, they may attack the client computer to disable it, and use IP spoofing to claim to be the client who was just authenticated and steal the session.

This attack can be prevented if the two legitimate systems share a secret which is checked periodically during the session. This attack can succeed under the right conditions, but may not be real practical as an attack form. The attacker will send incorrect DNS information which can cause traffic to be diverted. This attack can be used to divert users from a correct webserver such as a bank and capture information from customers when they attempt to logon. Password cracking - Used to get the password of a user or administrator on a network and gain unauthorized access.

To improve productivity, the DNS server caches the most recent data for quick retrieval. This cache can be attacked and the information spoofed to redirect a network connection or block access to the Web sites ,a devious tactic called DNS cache poisoning. The best defence against problems such as DNS cache poisoning is to run the latest version of the DNS software for the operating system in use.

New versions track pending and serialize them to help prevents spoofing. They are instead designed to render it unusable. Attackers can deny service to individual victims, such as by deliberately entering a wrong password 3 consecutive times and thus causing the victim account to be locked, or they may overload the capabilities of a machine or network and block all users at once.

There are also commonly vulnerabilities in applications that cannot be used to take control over a computer, but merely make the target application malfunction or crash. This is known as a denial-of-service exploit. The hacker sends a command to the master, which resides in any of the many hosts.

The master communicates with the agents residing in other servers to commence the attack. DDoS are harder to combat because blocking a single IP address or network will not stop them. The traffic can derive from hundred or even thousands of individual systems and sometimes the users are not even aware that their computers are part of the attack. After gaining access to your network, the attacker can do any of the following: Randomize the attention of your internal Information Systems staff so that they do not see the intrusion immediately, which allows the attacker to make more attacks during the diversion.

Send invalid data to applications or network services, which causes abnormal termination or behaviour of the applications or services. Flood a computer or the entire network with traffic until a shutdown occurs because of the overload. Block traffic, which results in a loss of access to network resources by authorized users. By using someone else's computer to launch an attack, it becomes far more difficult to track down the actual attacker.

Another common technique is to boot an operating system contained on a CD-ROM or other bootable media and read the data from the harddrive s this way. The only way to defeat this is to encrypt the storage media and store the key separate from the system. When an attacker is eavesdropping on your communications, it is referred to as sniffing or snooping. The ability of an eavesdropper to monitor the network is generally the biggest security problem that administrators face in an enterprise.

Without strong encryption services that are based on cryptography, your data can be read by others as it traverses the network. In certain cases, it is possible for an IP address to be falsely assumed— identity spoofing. An attacker might also use special programs to construct IP packets that appear to originate from valid addresses inside the corporate intranet.

After gaining access to the network with a valid IP address, the attacker can modify, reroute, or delete your data. Older applications do not always protect identity information as it is passed through the network for validation. This might allow an eavesdropper to gain access to the network by posing as a valid user. When an attacker finds a valid user account, the attacker has the same rights as the real user. Therefore, if the user has administrator-level rights, the attacker also can create accounts for subsequent access at a later time.

After gaining access to your network with a valid account, an attacker can do any of the following: Obtain lists of valid user and computer names and network information. Modify server and network configurations, including access controls and routing tables.
