This conditional access helps protect the corporate network from unauthorized access and potential threats.

Firewalls and VPNs

Firewalls act as barriers that regulate and monitor incoming and outgoing network traffic based on established security protocols. They filter network traffic by blocking suspicious traffic and allowing approved traffic based on a set of rules.

VPNs secure remote access by establishing encrypted connections, protecting data over public networks. Together, firewalls and VPNs create a robust security posture for networks, safeguarding data and communication.

Intrusion prevention systems (IPS)

Intrusion Prevention Systems (IPS) are crucial in network security for stopping or blocking suspicious traffic. They actively monitor network traffic to detect and block potential threats before they can exploit vulnerabilities.

In addition to blocking threats, IPS can alert administrators about suspicious activities, enhancing threat detection and response speed.

What is endpoint security?

Endpoint security focuses on protecting endpoint devices like desktops, laptops, and mobile phones from cyber threats. It aims to protect end-user devices from malware, unauthorized access, and data breaches.

Compromised endpoints expose data and provide back door access to networks, making endpoint security vital to prevent attackers from gaining a foothold.

The evolution of endpoint security has shifted from basic antivirus solutions to advanced systems capable of combating zero-day threats.

Effective endpoint security leverages tools, processes, and policies for threat detection, prevention, and response.

These measures safeguard critical infrastructure and enhance system performance by reducing downtime and disturbances.

Endpoint detection and response (EDR)

Endpoint Detection and Response (EDR) solutions continuously monitor endpoints, analyzing threats and providing real-time responses.

EDR systems focus on real-time monitoring and automated response to security threats, utilizing machine learning to enhance threat detection capabilities.

This enables immediate action, preventing significant damage from threats.

Antivirus and encryption

Antivirus is a type of endpoint security that specifically focuses on detecting and mitigating malware threats.

Traditional Antivirus primarily detects known threats, while Next-generation Antivirus (NGAV) identifies new threats by analyzing abnormal behavior on devices.

Data encryption encodes data into an unreadable form using a key, ensuring sensitive information remains protected.

OS update management

Regular operating system updates are vital to protect against known vulnerabilities.

Using outdated operating systems can provide cybercriminals with an entry point into systems, making routine updates and patches essential for fixing vulnerabilities and enhancing endpoint security.

How network and endpoint security work together

Integrating network and endpoint security strengthens the defense against cyber threats.

Endpoint protection platforms prevent vulnerabilities and threats introduced by endpoints, while central management tools facilitate data distribution between network and endpoint security.

Complete visibility of users, devices, and data across networks and endpoints is necessary for effective security management.

A defense-in-depth strategy is necessary to maximize the effectiveness of cybersecurity initiatives.

Integrated threat intelligence

Sharing threat intelligence between network and endpoint systems enhances overall security capabilities.

Collaboration between network and endpoint security systems improves the organization’s ability to detect and respond to cyber threats.

Comprehensive visibility and control

Integrating threat intelligence with automated prevention significantly enhances the organization’s security posture.

Centralized visibility into network activities allows for quicker threat detection and response, utilizing Security Information and Event Management (SIEM) systems to collect and analyze log data across the network.

Key technologies in network security

Key technologies used in network security solutions include network segmentation, secure remote access, and advanced threat detection.

A network security system, along with network firewalls, network security tools, and secure web gateways, are examples of network security products that help protect against cyber threats.

Traffic analysis evaluates network communications for known attacks, patterns, and invalid packets, providing information relevant to future detections.

Network segmentation

Network segmentation involves dividing networks into smaller sections to enhance security and manageability.

Technologies used for network segmentation include Virtual LANs (VLANs) and subnetting, which help control traffic flow and limit the attack surface of the network.

Microsegmentation allows for granular isolation of workloads, improving security policy management.

Zero trust security

Zero Trust security operates on the principle of ‘never trust, always verify’.

It requires continuous authorization and authentication for users and devices accessing the network, emphasizing continuous verification for user and device access.

This ensures only authorized users and devices access the network.

Advanced threat detection

Advanced threat detection technologies help identify threats by comparing current traffic against established behavior baselines (anomaly-based detection) and using a library of known threat patterns (signature-based detection).

Investing in these technologies is essential to combat emerging cyber risks, as traditional security measures require continuous updates to remain effective.

Key technologies in endpoint security

Endpoint security solutions include firewall software, antivirus, and endpoint security tools.

Choosing the right endpoint security solution is vital, as the wrong choice can leave endpoints vulnerable and undermine network security efforts.
