Email Security Intrusion Detection System (IDS) As emails allow scripts to be embedded inside the device, it is easier for anyone to write a code, attach it to an email, then send it. Receivers It is a software or a device for closely monitoring a network for any tend to click this email which can comprise the device. malicious activity or intrusion at the network or the host. The most effective security methods include email spam filters with For a Network IDS, a signature-based detection method is used deep learning to filter domains that send spam. wherein it seeks certain patterns of known malicious instruction sequences by targeting new malware sequences. It relies on machine learning to develop a model of trusted activity, then compares it to the current activity. For the detection of intrusions at the host, a host intrusion detection system (HIDS) is used to run on the individual hosts of a network; therefore, it only monitors the inflow and outflow of traffic at the host. 06 Handout 1 *Property of STI  [email protected] Page 2 of 3  IT2221 Consequences of Internet and Network Failure Damaged Reputation Since the internet is a collection of interconnected networks, their If internet and network failures regularly occur, it negatively impacts failures share the same consequences for an organization.
