  Understand the Importance of Network Forensics in this this article Network Forensics is the implementation of sniffing, recording, acquisition, and analysis of network traffic and event logs to investigate a   network security   incident. Capturing network traffic over a network is simple in theory, but relatively complex in practice due to many inherent reasons such as the large amount of data flow and complex nature of Internet protocols. Recording network traffic involves a lot of resources. It is often not possible to record all the data flowing through the network due to the large volume. Again, these recorded data need to be backed up to free recording media and for future analysis. The analysis of recorded data is the most critical and time-consuming task. There are many automated analysis tools for forensic purposes, but they are insufficient, as there is no foolproof method to recognize bogus traffic generated by an attacker from a pool of genuine traffic.

Information Security Incidents may be a network or host activity that potentially threatens the Information Security Incidents of knowledge. Keep on network devices and systems with regard to confidentiality, integrity, and accessibility. It’d be any real or suspected adverse event in regard to the safety of laptop systems or networks. It’s a violation or close at hand threat that has the potential to impact laptop security policies, acceptable use policies, or normal Information Security Incidents practices. Malicious Code or corporate executive  Threat Attacks:  Malicious code attack could be a kind of  attack   that’s generated by malicious programs like viruses, worm, and worms. Insiders can even use malicious code to realize body privileges, capture passwords, and alter audit logs to hide their tracks. Malicious code attacks also are referred to as as program threats. The intention behind this sort of attacks is to change or destroy the info, hide or st...

In this Sniffing article you will learn about Protocols vulnerable, Hardware Protocol Analyzers, Wiretapping and its methods, Types of Wiretapping and Lawful Interception Protocols vulnerable to Sniffing. Vulnerable to sniffing The following protocols are vulnerable to sniffing. The most reason for vulnerable to Sniffing these protocols is to accumulate passwords: Telnet   and   Rlogin Telnet may be a protocol used for communicating with a remote host (via port no. 23) on a network by using a instruction terminal. Rlogin enables an attacker to log into a network machine remotely via TCP connection. The protocols fail to supply encryption; therefore the data traversing between the clients connected through any of those protocols is in plain text and vulnerable to Sniffing, Attackers can sniff keystrokes including usernames and passwords. HTTP Due to  vulnerabilities  within the default version of HTTP, websites implementing HTTP transfer user data a...

In preparation for hacking a system, attackers follow a particular methodology. They first obtain information during the foot printing, scanning, and enumeration phases, which they then use to take advantage of the target system. There are three steps within the CEH Hacking Methodology (CHM): Gaining Access:- Involves gaining access to low-privileged user accounts by cracking passwords through techniques like brute-forcing, password guessing, and social engineering, then escalating their privileges to administrative levels, to perform a protected operation. Maintaining Access:- After successfully gaining access to the target system, attackers work to keep up high levels of access to perform malicious activities like executing malicious applications and stealing, hiding, or tampering with sensitive system files.  Clearing Logs:- To maintain future system access, attackers plan to avoid recognition by legitimate system users. to stay undetected, attackers w...
