Cyber attacks pose an existential danger to global businesses and government parastatals alike, and failure to safeguard their systems and networks can have disastrous results for the business.
Security measures like firewalls, intrusion detection systems and encryption should all be employed. Furthermore, employees need to be educated on cyber threats and proactive strategies for protecting themselves.
Intrusion Prevention System (IPS)
The Intrusion Prevention System (IPS) is a type of cyber security technology designed to block malware and other malicious threats from entering networks. It works by scanning all incoming network traffic for potential threats and alerting the system when detected.
IPS can detect attacks by either comparing the bitstream of network traffic with an existing signature database or by observing anomalies in traffic behavior. Anomaly-based detection is more precise than signature-based, but also produces more false positives.
IPS is an integral component of enterprise cybersecurity defenses, particularly in highly connected environments. By proactively screening through all traffic before it reaches other security devices and controls, IPS reduces their workloads and enables them to operate more efficiently – particularly for systems using anomaly-based monitoring.
Intrusion Detection System (IDS)
An IDS (Intrusion Detection System), a cybersecurity technology, scans the network for signs of unauthorized activity and alerts human security personnel when necessary. It has the capacity to detect security policy violations, viruses or configuration mistakes as well as notify human security personnel.
An IDS (Intrusion Detection System) can be either a hardware device or software application. It utilizes signatures of known malicious threats to detect incoming network traffic.
Another type of IDS is a host-based system, which monitors computer network traffic and its file set. It compares this new snapshot with its prior “snapshot” and alerts an administrator if there are major discrepancies in either set.
These systems can be purchased separately or as part of a comprehensive security suite. Cybersecurity experts suggest that small and midsize companies benefit most by incorporating an IDS into their larger platform.
Network Intrusion Detection System (NIDS)
Network Intrusion Detection System (NIDS) is a network security technology that monitors networks for suspicious activity. It utilizes sensors to passively inspect traffic, which may be hardware or software-based.
NIDS is often combined with Intrusion Prevention Systems (IPS) to offer organizations additional threat visibility. It also works in tandem with host-based intrusion detection systems (HIDS) and SIEM solutions to collect and analyze security events from multiple sources.
NIDS are essential elements in network security, protecting against malware, denial-of-service attacks and policy violations. They can quickly identify and respond to a wide range of cyberattacks that traditional firewalls cannot detect.
Intrusion Detection and Prevention System (IDPS)
An Intrusion Detection and Prevention System (IDPS) is an IT security solution designed to detect attacks before they take place. IPS solutions play a significant role in firewalls, antivirus software, and other cyber security technologies.
These systems monitor network traffic for signs of suspicious activity and compare signatures against known malicious attacks, as well as scanning network files for unusual patterns.
IDSs typically run on a single host, but some provide protection across multiple devices. They can monitor wireless or wired networking protocols as well as application protocols.
Although IDS systems can be highly effective, they also occasionally generate false alarms that necessitate IT teams to investigate and take corrective actions.
Network Security Monitoring (NSM)
Network Security Monitoring (NSM) is a type of cyber security technology that enables organizations to detect and respond to cybersecurity threats. It continuously scans network devices and traffic for vulnerabilities, threats, and suspicious activities.
NSM tools collect and analyze data associated with client-server communications, network payload, encrypted traffic sessions, and other operations to detect security threats. They also generate automatic alerts and reports that can help organizations take immediate actions to thwart cybersecurity breaches.
Some NSM strategies also incorporate automated update management for firewalls and malware scanners. This saves IT staff time and minimizes errors, while also guaranteeing security functions are present and up-to-date on every network endpoint.
