Endpoint security

Endpoint security tools protect devices like desktops, laptops, servers, and mobile devices that connect to corporate networks. Every device that connects to the network is a potential entry point for cybercriminals. Endpoint security aims to prevent malicious attacks, detect suspicious activities, and provide response capabilities from a central console. Core endpoint security solutions include:

Antivirus software – Detects and prevents malware like viruses, trojans, spyware, and ransomware.

Endpoint detection and response (EDR) – Monitors endpoints for suspicious activities indicative of advanced threats and automatically responds to security incidents.
Full disk encryption – Encrypts all data on endpoints to prevent unauthorized access.
Mobile device management – Secures and controls mobile devices accessing corporate resources.

Implementing layered endpoint security protects networks from malware, detects advanced attacks, and prevents data loss in case of device theft or loss.

Network security

Network security solutions provide threat protection for corporate networks and critical infrastructure. Core components include:

Firewalls – Inspect traffic and block threats while allowing benign traffic to pass through.

Intrusion prevention systems (IPS) – Scans traffic for malware and detects patterns indicative of attacks.
Web gateways – Filter inbound web traffic and block access to malicious websites.
Network access control (NAC) – Authenticates devices trying to connect to networks and limits access.

Data loss prevention – Prevents sensitive data from leaving the corporate network.

Multi-layered network defenses ensure that only authorized users and devices can access business-critical systems, while stopping threats and data exfiltration attempts.

Cloud security

Cloud security tools protect data and applications residing in public cloud platforms like Microsoft Azure, AWS, and Google Cloud Platform. Core cloud security measures involve:

Cloud access security broker (CASB) – Monitors cloud resource usage, detects threats, and enforces security policies.
Cloud workload protection platforms – Provide runtime security for workloads against malware and unauthorized activities.
Cloud encryption – Encrypts data at rest stored in the cloud and in transit between cloud apps.

Cloud identity and access management – Manages access to cloud resources and protects credentials.

A recurring theme in cloud security is extending existing on-premises security controls to the cloud. Cloud adoption is increasing, so enterprises need robust cloud security to avoid data breaches.

Email security

Email continues to be the top infection vector for malware and phishing attacks. Core email security technologies include:

Secure email gateways – Inspect all inbound and outbound emails for threats and filter malicious emails.
Email encryption – Encrypt email to protect sensitive data from unauthorized access.
Anti-spam and anti-phishing tools – Block unwanted commercial emails and phishing emails aiming to steal user credentials.

Email authentication – Validate sender identities to prevent spoofing, business email compromise (BEC), and other social engineering schemes.

Robust email security is a must-have to protect against social engineering, ransomware, data exfiltration via email attachments, and other email-borne threats targeting employees.

Web security

Web traffic is one of the key sources of external threats entering corporate networks. Web security solutions include:

Secure web gateways – Inspect all inbound web traffic for malware, block malicious sites, and enforce acceptable web use policies.
Web application firewalls – Protect web applications from injection attacks, cross-site scripting, and application exploits.
Botnet protection – Blocks botnet communications to infected hosts, preventing them from being weaponized.

Web security closes an important threat vector and allows enterprises to control employee web use. Extending web security to remote users is also important for hybrid work environments.

Data security

Data security encompasses protecting data at rest, in motion, and in use. Key technologies include:

Data loss prevention – Stops sensitive data exfiltration and unauthorized access to critical data.

Full disk and file encryption – Renders data unreadable without authorized access.
Digital rights management – Controls usage of confidential documents shared externally.
Data masking – Anonymizes portions of sensitive data to make it safe for use in testing environments.

Considering the value of data to enterprises, comprehensive data security reduces the risks and impact of data breaches.

Identity and access management (IAM)

IAM establishes access controls for user authentication and authorization to corporate resources and data. Core IAM technologies include:

Multi-factor authentication (MFA) – Requires multiple factors like biometrics and one-time passwords to verify user identities.

Single sign-on (SSO) – Simplifies login across applications using one set of credentials.
Privileged access management – Secures credentials for admin accounts and monitors the activities of privileged users.
Identity governance – Provisions and deprovisions user access to enterprise systems based on roles.

IAM increases security and simplifies access to authorized users while reducing the attack surface for malicious actors.

Security operations center (SOC)

An in-house SOC consists of people, processes, and technology focused on detection, investigation, and response to security threats. Key SOC components include:

Security analysts – Monitor networks, endpoints, logs, and alerts to detect indicators of compromise.

Security orchestration and automation tools – Automate repetitive tasks like blocking IPs, killing processes, and resetting credentials.
Security incident and event management (SIEM) – Collect and correlate data from security tools to provide visibility into threats.

An effective SOC provides 24/7 vigilance, rapid detection and response, and in-depth investigation of security incidents. Managed security service providers (MSSPs) also offer SOC-as-a-service for organizations lacking in-house expertise.

Third-party risk management

Third-party vendors like suppliers, partners, contractors, and acquisitions can introduce new cyber risks to an organization. Third-party risk management aims to address this by:

Maintaining a third-party inventory to identify all vendor relationships.
Conducting risk assessments of third-parties based on their access to sensitive data.

Performing security audits and due diligence on high-risk vendors.
Including security requirements in contracts with liability clauses for data breaches.

Managing third-party cyber risk is critical as part of an enterprise-wide security program.

Security awareness training

Users are often the weakest link in security, accidentally introducing threats into corporate networks. Security awareness programs aim to educate employees on cyber risks through:

New hire orientation – Introduce new employees to security best practices.
Ongoing simulated phishing attacks – Test employee responses to identify vulnerabilities.

Lunch and learn events – Engage employees with interactive sessions on security.
Posters and newsletters – Use visual collateral to remind employees of risks.

Security awareness training should be continuous – not just a one-time activity – to account for new cyber schemes and refresh employees’ understanding of policies.

Incident response planning

Despite best efforts, some security incidents will inevitably occur. Incident response planning involves:

Documented policies and procedures for detecting, responding to, and recovering from security events.
Established roles and responsibilities for incident response team members.

Communication plans for reporting incidents to leadership and affected parties.
Cyber insurance to cover costs associated with data breaches.

Proper planning enables a swift, coordinated response that minimizes business disruption and damage to the organization.

Penetration testing

Penetration testing, also called pen testing or ethical hacking, involves authorized cybersecurity professionals attempting to penetrate networks and systems to uncover vulnerabilities before they are found by attackers. Key aspects of pen testing include:

External testing – Simulates outside attacks from the internet against public-facing apps and infrastructure.
Internal testing – Emulates insider threats from trusted employees within the network.

Social engineering – Targets employees to gain access or information through deception.
Vulnerability scanning – Systematically scans apps and networks for known flaws.

Regular pen testing provides insight into real-world vulnerabilities that need remediation.

Backup and disaster recovery

Backup and disaster recovery (DR) provides the capability to restore systems, apps, and data in the event of outages, natural disasters, cyber attacks, and other crises. Elements include:

Backups – Make copies of critical data and systems on separate storage media.
Alternate business site – Provides temporary facilities to continue operations if primary site is unavailable.

Failover systems – Switches operations from primary to backup infrastructure when systems fail.
Emergency communications – Contact trees, toll-free numbers, and other means of connecting with staff during disruptions.

Resilient backup and DR ensures enterprises can stay in business despite adverse circumstances.

Secure software development

Many data breaches originate from vulnerabilities in application code exploited by attackers. Secure software development life cycle (SDLC) introduces security at every phase of the development process:

Requirements – Identify compliance needs and security requirements like encryption and access controls.
Design – Apply secure design principles and threat model potential risks.

Coding – Adhere to secure coding practices and static code analysis.
Testing – Perform extensive security testing and code reviews before deployment.
Deployment – Follow secure deployment and key management processes.

Making security a shared responsibility across the entire development team results in more secure software.

Security compliance

In regulated industries, security compliance is mandatory. Compliance frameworks like PCI DSS, HIPAA, SOC2, FedRAMP, and ISO 27001 outline security controls and best practices. Key compliance activities involve:

Asset inventory – Catalog all systems, data, and technical dependencies in scope for compliance.

Gap assessment – Compare existing security measures against compliance controls to identify deficiencies.
Remediation – Fix gaps by implementing required policies, technologies, and processes.
Audits – Obtain independent validation that all necessary controls are in place and effective.

Security compliance provides assurance to customers and regulators that data security meets industry standards.
