Threats to TCP/IP Security
ثبت نشده
چکیده
Because of this increased focus on network security, network administrators often spend more effort protecting their networks than on actual network setup and administration. New tools that probe for system vulnerabilities, such as IIS (Internet Security Scanner) assist in these efforts, but these tools only point out areas of weakness instead of providing a means to protect networks. Thus, as a network administrator, you must constantly try to keep abreast of the large number of security issues confronting you in today's world. This section describes many of the security issues that arise when connecting a private network to the Internet.

Low Rate TCP Shrew Attacks: Threats and Solutions
On the global Internet, the main function of TCP is to provide a reliable byte stream process to process communication. Today, TCP is the most widespread protocol used for exchanging data in the Internet and almost responsible for more than 90 percent of the world’s total data traffic on the Internet. Despite its widespread usage, many of the TCP protocols were designed with little consideratio...
متن کاملIntrusion Prevention: The Future of VoIP Security
Voice-over-IP (VoIP) technology has come of age and is quickly gaining momentum on Broadband networks. VoIP packetizes phone calls through the same routes used by network and Internet traffic and is consequently prone to the same cyber threats that plague data networks today. These include denial-of-service attacks, worms, viruses, and hacker exploitation. In addition to these traditional netwo...
متن کاملA Off-Path TCP Injection Attacks
TCP is the main transport protocol over the Internet, ensuring reliable and efficient connections. TCP is trivially vulnerable to man-in-the-middle (MitM) attackers; they can intercept, modify and inject TCP traffic [Joncheray 1995]. Despite significant possible threats, a common assumption is that MitM capabilities are difficult to obtain; this assumption is demonstrated by OWASP’s list of top...
متن کاملTCP/IP Attacks, Defenses and Security Tools
The TCP/IP protocol suite is the foundation of Internet and is ubiquitous in almost all networks worldwide. It was written as a robust protocol, which is able to communicate despite node failures. The design parameters of TCP did not weigh security as important and placed an implicit trust on nodes. The result was a protocol which was reliable and robust, but contained myriad inherent security ...
متن کاملSecurity Strategies for SCADA Networks
SCADA systems have historically been isolated from other computing resources. However, the use of TCP/IP as a carrier protocol and the trend to interconnect SCADA systems with enterprise networks introduce serious security threats. This paper describes two strategies for securing SCADA networks, both of which have been implemented in a laboratory-scale Modbus network. The first utilizes a secur...
