What is Zero Trust Isolation and Why It’s Needed?
It is virtually impossible to predict ransomware attacks. Malicious actors use security holes in corporate IT networks to find vulnerable devices, gain unauthorized access to them, and then use this access to spread malware and ransomware to other devices on the network. These attacks can originate from a variety of sources, including phishing emails, which are phony emails that hackers use to access a person’s computer. Attackers have even been known to enter workplaces while posing as visitors or employees in order to connect to the networks and gain access.
What is MACsec?
The goal of IEEE 802.1AE1 MACsec is to establish secure a secure link from one Ethernet device to another. This protects Ethernet frames from attacks such as sniffing, snooping, spoofing, and Man-in-the-Middle (MitM), which represent 35%2 of all exploits. MACsec is an encryption standard operating at Layer 2 within the OSI model that provides a secure bi-directional communication link. Protecting against growing threats, the use of MACsec ensures the confidentiality, authenticity, and integrity of Ethernet traffic, protecting data from being tampered with or eavesdropped on without permission. As MACsec operates at Layer 2, it offers enhanced security protection in a high-bandwidth environment without affecting network or CPU performance.
What Are WIDS and WIPS?
WIDS stands for wireless intrusion detection system. It is a technology designed to protect wireless networks from unauthorized access. It does this by monitoring traffic on the network to identify any suspicious activity that may indicate a security breach. WIPS stands for wireless intrusion prevention system. WIPS uses a combination of techniques to detect and prevent intrusions in real time. It not only monitors but also takes action to prevent rogue access points, man in the middle attacks, denial-of-service attacks, and other threats to the wireless network.
What Is Network Encryption? How Does It Work?
Network encryption is a method used to secure data that is being transmitted over a network, both internally within a company and externally across the internet. This is achieved by converting the readable data into unreadable data. This data can only be made readable in the format of a decryption key. The main purpose of network encryption is to prevent unauthorized access to data as it moves across the network. It is crucial to protect sensitive information from being intercepted during transmission. It is commonly used in many online processes, such as online banking and e-commerce transactions, to protect data integrity and user privacy.
Man-in-The-Middle (MitM) Attack: Definition & Defenses
A Man-In-The-Middle (MITM) attack is a type of cybersecurity breach that occurs when a hacker intercepts communication between two systems, usually a user's device and a server or website. The attacker is then able to eavesdrop, capture, and manipulate the data that is being exchanged. This could involve stealing sensitive information such as login credentials, credit card numbers, or personal identity data. The attacker can also alter the communications, misleading the user or server, often without either party knowing that the attack has occurred.
What Is Wi-Fi Security? WEP, WPA, WPA2 & WPA3 Differences
Wi-Fi security refers to the protection of Wi-Fi networks and connected devices from unauthorized access, data breaches, hacking, and other potential cyber threats. It involves implementing security measures, such as encryption, authentication, and security protocols, to protect the data that is transmitted in a wireless network, its users / devices and the network infrastructure that it is connected to. Wi-Fi security protocols like Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2, and WPA3 are designed to provide different levels of security. For instance, WEP is the oldest and least secure, while WPA3 is the latest and most secure protocol.
What Is a Wireless Intrusion Detection System (WIDS)?
A wireless intrusion detection system (WIDS) is a security solution specifically designed to detect anomalous activities, intrusion attempts, and vulnerabilities within a wireless network. It can identify possible attacks, unauthorized access, or misconfigurations in the network. WIDS accomplishes this by monitoring radio frequencies for specific packet patterns or behavior associated with malicious activities. It plays a crucial role in enforcing network security policies and protecting against threats such as rogue access points, identifying weak encryption methods, and weak or default passwords for pre-shared key authentication mechanisms.
What Is Network Security? Types & Importance Explained
Network security encompasses a wide range of technologies, procedures, and protocols strategically crafted to safeguard the integrity, confidentiality, and availability of computer networks and the associated data. This involves implementing measures to prevent and monitor unauthorized access, misuse, alteration, or denial of the network and its resources. Network administrators typically achieve this through a combination of hardware devices, such as routers and firewalls, and software programs, such as antimalware tools. Techniques used in network security include data backup, encryption, user authentication, intrusion detection systems, and continuous network monitoring.
