Make regular backups. c. Use of Antivirus / Anti Malware and other software assist in blocking a Scareware threat. d. Software should always up to date such as flash, Java etc. e. If computer is infected, immediately un-plug the network cable and shut the computer down, so that the network should not be affected. f. Users should be trained to identify threat and take effective measures for resolving it.
INTRODUCTION TO NETWORK SECURITY ABSTRACT Network security is protection of the files and directories in a computer network against hacking, misuse and unauthorized changes to the system. Network security involves the authorization of access to data in a network which is controlled by the network administrator. Users are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Today almost anyone can become a hacker by downloading tools from the internet. Nowadays security is becoming vital in case of networking because everyday a new kind of attack is generated which leads to compromise our network and have security in network is decreasing because
While transmitting and storing your test results it can be very critical. If it is possible try to encrypt the e-mails and files using Pretty Good Privacy (PGP) or something similar. Now you are on a reconnaissance mission. Try to harness as much information as possible about your organization and systems, which is what malicious hackers do.

Potential criminal electronic attacks on computer software, such as destructive "viruses" or "Trojan Horse" software, create a serious threat to Internet voting. To minimize the potential technological threats to Internet voting, election officials should provide unique operating system and web browser software to voters. 2). To achieve the required level of security for a remote Internet ballot, voters will be required to take several precautionary steps before voting. For remote Internet voting to be successful, the burden of the additional duties placed on voters must not outweigh the benefits to be derived from the increased flexibility provided by an Internet voting system.
In this phase hacker logs on to the target system on root or admin mode and upload a piece of code(usually called backdoor or Trojan) on the organization’s network. After that the hacker could able to connect with the system. The last stage or phase is covering tracks. In this stage hacker usually clear all the logs and the backdoors so that he not to get caught. The server maintains a log file anyone who logged on to the system and thus a hacker may be caught.
All what he needs is a computer supplied by a wireless network adapter working on promiscuous mode to allow a network device to intercept and read each network packet that arrives even with other network address, to be in the area of the wireless network coverage and to have one of the particular software tools that allows the eavesdropping. Figure 2: Process of Eavesdropping Types of Attacks: Classes of attack might include passive monitoring of communications, active network attacks, close-in attacks, exploitation by insiders, and attacks through the service provider. Information systems and networks offer attractive targets and should be resistant to attack from the full range of threat agents, from hackers to nation-states. A system must be able to limit damage and recover rapidly when attacks occur. There are five types of attack: 1.)
The firewall protects an organization from malicious attacks from the Internet and the Intrusion detection system detects if someone tries to break in through the firewall or manages to break in the firewall security and tries to have access to any system in the trusted side and alerts the system administrator in case there is a breach in security. Moreover, Firewalls do a very good job of filtering incoming traffic from the Internet; however, there are ways to circumvent the firewall. For example, external users can connect to the Intranet by dialing in through a modem installed in the private network of the organization. This kind of access would not be seen by the
2: check computer application and remove problems: We need to check computer applications properly. We should install some virus detective applications in our system to protect it from that issue which brings DPC watchdog violation blue screen dead errors. 3: antivirus scans to remove and delete affected
