What Are Rogue Devices? How to Detect and Prevent Them
Rogue devices are unauthorized devices that connect to a network without permission. They can include any type of device that is capable of network connection, like smartphones, laptops, and even Internet of Things (IoT) devices. Rogue devices pose a major security risk as they are potential sources of data breaches or malware infections. These devices might be introduced to the network by employees without harmful intentions or by malicious actors aiming to steal data or conduct other harmful activities. They can also cause network performance issues by consuming bandwidth.
Secure Network Authentication Methods, Types and Protocols
Network Authentication is a process that verifies and confirms the identity of a user, device, or system trying to access a network. This is often achieved through the use of login credentials such as usernames and passwords. The main objective of network authentication is to prevent unauthorized access, ensuring only authenticated users or systems can access network resources and data. Network authentication is a fundamental aspect of network security and can be implemented through various methods such as two-factor authentication, biometric authentication, and digital certificates among others.
Top Network Attacks & Threats (And How to Protect Yourself)
A network attack involves an effort to obtain unauthorized entry into an entity's network, typically with the objective of disrupting operations, stealing information, or tampering with data. These attacks can take various forms and are executed with malicious intent, posing significant threats to the security and integrity of digital assets. Network attacks are a serious concern for businesses and individuals alike, as they can result in data breaches, financial losses, and damage to reputation. Understanding the nature of network attacks is essential for implementing effective security measures.
What Is Network Segmentation? How It Works & Why It Matters
Network segmentation is dividing a computer network into smaller subnetworks or segments. Each segment can act as its own small network, which can help increase network performance and enhance security. Network segmentation allows for better control over traffic flows and isolates network issues, reducing the impact on the whole network. It can also help prevent unauthorized access to sensitive information by keeping that information on a separate segment isolated from general network traffic.
What Is IEEE 802.1X for Zero Trust Access?
Today’s networks are vulnerable to excessive attacks. The principles of zero trust are the gold standard organizations use to protect apps and data. A key element of zero trust access is “trust no one, authenticate everyone”. However, current application-specific or client-specific Zero Trust Access controls do not provide an adequate level of protection for all devices on the network. In order to extend zero trust into the campus network, every wired and wireless connection must be authenticated and authorized using at least one mechanism such as IEEE 802.1X, MAB, Behavioral MAB and Single Sign On. Here, we explore how IEEE 802.1X helps in accomplishing zero trust access for the enterprise campus network. IEEE 802.1X provides the authentication framework for user devices before granting access to the Local Area Network (LAN).
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.
