Network & Endpoint Security

Enterprises need a simpler, scalable, threat-centric approach to endpoint security that provides visibility and control of threats before, during, and after they occur.
Every device that employees use to connect to enterprise networks represents a potential risk that cyber criminals can exploit to steal your organization’s data. The number and variety of endpoints is growing, so the task of continuously securing them becomes increasingly more challenging. As this security perimeter expands, organizations realize the necessity of developing and implementing a comprehensive cybersecurity strategy that integrates their network security and endpoint security efforts.

Synchronizing the deployment and coverage of network and endpoint security solutions creates a defense in depth strategy. Defense in depth is the coordinated use of multiple security countermeasures to better protect the integrity of the network and its users, data, and assets from cybercriminals.

Endpoint Security

What Is Endpoint Security?

Endpoint security refers to cybersecurity services for network endpoints. These security solutions include antivirus, email filtering, web filtering, Intrusion Detection Service (IDS), Intrusion Prevention Services (IPS), and firewall services. Endpoint security plays a vital role for organizations by securing critical systems, intellectual property, customer data, employees, and guests from ransomware, phishing, malware, and other forms of cyberattack.

Endpoint security combines preventative protection with continuous detection and response capabilities to secure end-user endpoints, such as desktops, laptops, mobile phones, tablets, and Internet of Things (IoT) devices, from zero-day threats, sophisticated malware, and evolving cyberattacks. Endpoint security is also an integral component of the modern defense in depth strategy.

Endpoint protection systems are designed to quickly detect, analyze, block, and contain cyberattacks in progress. By integrating endpoint security and network security, IT administrators have visibility into advanced threats and information to quickly detect security risks and improve cyber threat detection and remediation response times.

What Are Endpoint Security Components?

The main components of an endpoint security solution are:

  • Device Protection: Advanced antimalware and antivirus applications to protect, detect, and correct malware across multiple endpoint devices and operating systems
  • Endpoint Encryption: Endpoint, email, and disk encryption to prevent data leaks and unauthorized external transfer of data from a computer or other device
  • Application Controls: Application controls prevent endpoint users from executing unauthorized applications and block risky activities that could create vulnerabilities across the network
  • Browser Protection: Proactive web security to ensure safe browsing on the web, including filtering to identify the types of sites network users are allowed to access
  • Email Gateways: Email gateway to block suspicious messages, phishing scams, ransomware, and social engineering attempts
  • Network Controls:
    • Firewall – A comprehensive, integrated firewall that filters all incoming traffic and identifies potential risks.
    • Endpoint Management – Centralized endpoint management platform to improve visibility and simplify operations
    • Threat Intelligence System – Using artificial intelligence and machine-learning classifications to detect zero-day threats in near real time
  • Data Controls: Insider threat protection using data classification and data loss prevention policies to safeguard against unintentional and malicious data loss
  • Forensic Analysis: Actionable threat forensics allow administrators to probe deeper into potential security problems, diagnose where and how malware entered into the network, quickly isolate infections, and remediate the intrusion
  • Internet of Things (IoT) Protection: Advanced antimalware and antivirus applications for smart, IoT enabled devices to protect, detect, and correct malware

What Are The Benefits Of Endpoint Security?

Digital transformation initiatives, the move to the cloud, and a rapidly expanding attack surface are driving the need for a new class of endpoint security, capable of defending organizations against a more diverse and sophisticated threat landscape.

Some of the key benefits of modern endpoint security solutions include:

  • Endpoint Protection: Ensure secure end-user access to the organization’s data
  • Remote and Hybrid Work Security: Enforce remote and hybrid work policies and device usage (e.g., bring your own device (BYOD))
  • Defense in Depth Threat Protection: Protect and secure access from bad actors using sophisticated cyberattacks attempting to gain access to corporate networks, steal data, and manipulate employees into providing sensitive information
  • Identity Protection: Linking endpoint security to employees’ devices, enabling them to work safely when connecting to the enterprise network data and resources
  • Endpoint Detection and Response: Monitoring people-centric device behavior over time and alerting IT administrators when a device or group of devices deviates from baseline normal behavior
  • Endpoint and Network Security Integrations: Threat information collected and analyzed by endpoint security tools is shared with network security tools to automatically update security policies to protect against any identified threat.
  • Endpoint Security Compliance: Adherence to corporate governance data security standards reduces and manages risk and advances regulatory compliance efforts

Networking For Future (NFF) Solutions

Selecting the best endpoint security solution for an organization requires first understanding how the organization’s end-users interact with the various network elements.  NFF performs a comprehensive security assessment of the network to determine its access points and who needs access to what resources.  With this information, it is easier to develop an enhanced network security solution.

With the endpoint security survey and catalog, the defense-in-depth plan will document the security solution for every layer of the threat landscape, including the hardware, software, cloud, and network elements.

For organizations that need to review their existing network and endpoint security defenses, NFF offers a comprehensive network security architecture consultation service. This comprehensive engagement assesses the capabilities and requirements throughout the network and provides a single view of what is needed to build a more complete cybersecurity architecture to help achieve the organization’s strategic goals.

The NFF solutions for the modern security threat landscape challenges include:

  • Security Data Analytics: Analyzes security intelligence data to easily investigate incidents, find advanced persistent threats, and remediate the intrusion
    • Splunk Enterprise and SIEM use big data analytics to analyze an organization’s machine-generated security data. It integrates information and reports across vendor’s equipment and platforms.
    • Network-as-a-Sensor gathers summary data of all network transactions to look for anomalies in the traffic patterns that could be caused by advanced persistent threats (APTs) and assists in investigating incidents
    • Domain Name System (DNS) Intelligence inspects domain resolution information and uses real-time contextual DNS information to reveal ongoing cyberattacks
  • Trusted Identity Services: Enforces data access policies on the network for network users and endpoints
    • Network Access Control ensures that wireless, wired, and remote networks allow their users and devices only the connectivity required
    • Guest Lifecycle Management establishes options for network connectivity to guest users through self-service and sponsored access mechanisms.
    • Mobile Device Management makes certain organizational security policies are enforced on devices that access protected data
  • Content Filtering: Enforces policy requirements and enhances safeguards through screening email and web traffic content
    • Web Content Security provides outbound web proxy features with the use of advanced security protection, acceptable-use enforcement, and robust reporting delivered via on-premises and/or cloud deployments
    • Email Security couples traditional anti-SPAM features with using the latest security intelligence to block malicious attachments and hyperlinks within emails
  • Security Threat Defenses: Defends end-users against modern security threats wherever they are, using whichever device they choose. For example:
    • Next-Generation Firewalls (NGFW) provide application visibility and control on top of existing address/port control features found in standard firewalls today.
    • Intrusion Detection/Prevention (IDS/IPS) scans traffic on the network and analyzes it to find any traffic patterns that match known attack vectors.
    • Web Security enforces a set of policies that prevent systems from compromise by preventing communications with known malicious, or otherwise untrusted, websites.
    • Advanced Malware Protection provides visibility and control of the software transferred on the network or running on endpoints, preventing known malware and continuously analyzing and recording actions of other yet-unknown files.
    • DNS-Based Visibility and Control gives organizations another layer of protection for their end-users through intelligence in DNS name resolution, on or off the network.
    • Unified Threat Managers (UTM) provide a streamlined, single-box solution for smaller IT organizations to deliver many of the security threat defenses above.

Choosing the wrong endpoint security solution can leave your users vulnerable to threats and impede, or undo, the significant work that has gone into securing the network. Your endpoint security solution should secure all endpoints continuously, as well as bring additional capabilities to other parts of the organization and improve your network security posture.
