Network Security Systems are the backbone of protecting an organization's digital assets and encompass a broad range of technologies, methodologies, and practices designed to protect the integrity, confidentiality, and accessibility of networks and data using both hardware and software solutions.
Network Security Systems are tools and technologies designed to protect a computer network from unauthorized access, misuse, or denial of service attacks. These systems provide robust security measures to ensure data integrity, confidentiality, and availability.
Solutions within this category include:
- Firewalls: Prevent unauthorized access to a network.
- Intrusion Detection Systems (IDS): Monitor network traffic for suspicious activity.
- Virtual Private Networks (VPN): Securely connect remote users to a network.
- Antivirus software: Detect and remove malware from network systems.
- Encryption tools: Securely transmit sensitive data over a network.
- Two-factor authentication: Enhance login security by requiring multiple forms of verification.
A firewall is a device used for network security. It monitors network traffic (both incoming and outgoing) and then, based on a set of security rules, either permits or blocks data packets.
What is advanced threat protection? Advanced Threat Protection (ATP) consists of the group of practices and tools used to prevent advanced cyber attacks. Usually, ATP solutions will combine network devices, web gateways, endpoint agents, malware protection systems, and a centralized management dashboard. The solutions can be delivered as software or as managed services.
ZTNA as a Service is a cloud-based security solution that provides secure access to applications and data from anywhere, helping organizations protect themselves from data breaches and other security threats.
What is an enterprise VPN? An enterprise VPN (virtual private network) helps companies large or small to access their resources safely, regardless of where they are hosted - either locally or in the cloud. Sometimes known as cloud VPNs or VPNaaS (VPN as a service), enterprise VPNs protect an organization’s sensitive assets when employees need to access them using unfamiliar or unsafe wifi connections or are connecting via different unrecognized devices. Enterprise VPNs radically increase security, improve bandwidth, and expand your overall network’s reliability. In other words, enterprise VPNs are essential for organizational networks and offer companies a solution that is scalable and secure, while providing the safety needed for employees to be able to work remotely.
What Is an Intrusion Detection System? Intrusion detection systems (IDSes) analyze network traffic for signatures of known attackers. The systems can be hardware devices or software solutions. An IDS can mitigate existing malware, such as backdoors, rootkits, and trojans.
The goal of an intrusion detection system is to detect an attack as it occurs. The system starts by analyzing inbound and outbound network traffic for signs of known attackers.
What is a Unified Threat Management System? A UTM is an all-in-one information security approach in which a single converged platform (application or appliance) provides multiple security services. This can resolve implementation and integration challenges that might result from using different products from different vendors. A UTM may include network firewalls, anti-spam, anti-spyware, anti-virus, intrusion detection and prevention, email and web content filtering, NAT (network address translation), and business VPN (virtual private network). Using a UTM simplifies information security (infosec) management, providing one central management and reporting point instead of multiple appliances from different vendors.
What is Zero Trust Network Access (ZTNA)? As working remotely has become more and more prevalent, it has become increasingly challenging to protect network resources since trust can no longer be granted based on location. Zero Trust Network Access (ZTNA) is the technology behind establishing a zero-trust model that ensures secure remote access regardless of where the user or application resides. ZTNA, also known as the software designed perimeter (SDP), operates on a model where trust is never implicit. It manages access authorizations at the application level and not at the network access level (as does the virtual private network or VPN). Although VPNs have been the de facto method of accessing corporate networks up until now, their limitations have created significant drawbacks for complex ecosystems.
What is network access control (NAC)? Network access control (NAC) is a type of security software solution that controls who can access a network and in what capacity. These security solutions provide network visibility and access management by enforcing the security policies on connected devices across the network.
What is Network Detection and Response (NDR)? Network detection and response (NDR) is a new category of cybersecurity solutions that focuses on monitoring network traffic, detecting, and responding to cyber threats.
What is microsegmentation? Microsegmentation is the latest current trend in security to protect data and reduce threat risk in operating systems and cloud environments. It is a security solution process that has been created to intuitively compartmentalize the data by workload within an organization’s operating systems. Security architects can develop protocols to define how all traffic moves throughout your ecosystem - north-south and east-west. It will also limit which devices can communicate with each other throughout your network. Microsegmentation can give increased granular control and keep designated segments completely secured and isolated while offering multi-dimensional firewall protection based on zero-trust policies.
What is firewall security management software? Firewall management is the group of actions and practices used for configuring and monitoring a firewall with the goal of maintaining network security. Firewalls are key elements used for protecting private networks.
What is IoT security? IoT (internet of things) security encompasses the protection of all physical devices, spanning from industrial machines and energy grids to entertainment devices, along with the networks they connect with.
What is an SSL VPN? A secure sockets layer virtual private network is known as an SSL VPN. An SSL VPN creates a secure and encrypted connection over a network that is less secure - for example, the internet. When connecting your mobile device or computer to a private network, a VPN conceals your IP address and establishes an encrypted connection that allows you to securely share data while simultaneously shielding your identity. SSLs work by converting private data or information into a combination of unreadable letters and numbers. By using end-to-end encryption, SSL VPNs ensure protection from a browser to the destination and then back again.
What is a session border controller? A session border controller, or SBC, is installed at the perimeter of a network or “border” to control communications (such as voice calls, video conferences, desktop sharing, etc.) that take place on a service provider IP (internet protocol) network. An SBC is designed to secure a session initiation protocol, otherwise referred to as SIP, which identifies when other parties are present and is responsible for establishing a connection, maintaining the connection, and terminating it when a session is finished. It does this by sending messages via data packets between SIP addresses or IP endpoints. An SBC also ensures that different SIPs are able to flawlessly work together. Without SBCs, systems may be unable to communicate effectively with other systems. SBCs are therefore considered indispensable when it comes to maintaining well-functioning IP communications.
Network Security Systems are crucial in protecting networks from potential threats and attacks. Organizations can implement several types of Network Security Systems to ensure the safety of their data and systems. These include:
1. Firewalls: Firewalls are a key component of network security, acting as a barrier between a trusted internal network and untrusted external networks. They monitor and filter incoming and outgoing network traffic based on predetermined security rules.
2. Intrusion Detection Systems (IDS): IDS are designed to detect and respond to unauthorized access or suspicious activities on a network. They can detect known threats and abnormal behavior that may indicate a potential security breach.
3. Intrusion Prevention Systems (IPS): IPS take network security a step further by not only detecting threats but also actively blocking or preventing them from infiltrating the network. They can analyze and respond to threats in real-time.
4. Virtual Private Networks (VPN): VPNs create a secure encrypted connection over a public network, such as the internet, allowing users to securely access and transmit data over the network. This is particularly important for remote workers accessing corporate networks.
5. Antivirus Software: Antivirus software is essential for protecting networks from malware, viruses, and other malicious software. It scans files and programs for known threats and removes or quarantines them to prevent damage to the network.
6. Data Loss Prevention (DLP): DLP systems help organizations prevent the unauthorized sharing or leakage of sensitive data by monitoring and controlling data transfers within the network. They can also detect and prevent data breaches.
7. Secure Sockets Layer (SSL) and Transport Layer Security (TLS): SSL and TLS protocols encrypt data sent over the internet to ensure secure communication between servers and clients. They are commonly used for secure online transactions and communication.
8. Endpoint Security: Endpoint security solutions protect individual devices, such as laptops, desktops, and mobile devices, from security threats. They include antivirus software, firewalls, and encryption to secure endpoints from potential vulnerabilities.
Implementing a combination of these Network Security Systems can help organizations create a robust defense against cyber threats and ensure the integrity and confidentiality of their network data.
