Select the Security Tech Stack you will Implement in your Cybersecurity Software

Security tech stack assists in implementing the cybersecurity plan any business plans to adopt. It includes all the required software platforms and tools needed to timely detect, mitigate, and counter cyber threats.

It ranges from simple antivirus and anti-malware software to complex DNS filters. Below we will discuss different security tech stacks and all their components in detail.

  • Perimeter security

Perimeter security protects an organization’s internal network from the external public network. Perimeter security is ensured through techniques like unified threat management and application firewalls.

Unified threat management is a robust approach to preemptively protect your system from threats and vulnerabilities trying to reach your system. It includes intrusion detection, content filtering, spam detection, etc.

A web application firewall is more focused on the data communication taking place between cloud applications and user applications for web attack prevention. 

As cloud computing is very popular today among businesses, cybersecurity developers adopt a web application firewall to ensure web security.

Your cybersecurity software development team should be familiar with perimeter security solutions like Cisco Meraki (UTM), Cloudflare (WAF)

  • Information security

Information security is required to prevent business data breaches and unintentional leakage. To ensure information security, your developers should be familiar with data loss prevention (DLP) and email security.

DLP focuses on preventing the unauthorized transfer of data out of the organization. It ensures this by performing extensive data labeling. It includes data storage, access, and sharing protocols.

Email security is focused on email communication. It prevents cyber security attacks like phishing, spam, virus-ridden emails, etc.

Your developers should be experts in information security solutions like Microsoft Azure DLP and Proofpoint, as anti-phishing tools.

  • Authentication Protocols

Authentication protocols help prevent unauthorized users from entering your computer system. These protocols, when effectively implemented, can prevent many security vulnerabilities. 

Your software development team should be experts in implementing authentication techniques like multifactor authentication and password management for application security.

Multi-factor authentication (MFA) ensures data security by using a secondary device for user authentication. It is widely used today for mobile app security and is modern security standard compliant for both ioS and Android.

MFA has proven helpful in preventing data losses and access breaches. According to Microsoft, MFA can prevent up to 90% of cyber attacks on user accounts.

Password management ensures that users are regularly updating their account login information with stronger passwords. The complete update history is tracked and encrypted for security purposes.

The authentication protocol solution providers your development team should be familiar with are DUO for multifactor authentication and Passportal as a password manager.

  • Backup and Disaster Recovery

This approach ensures that all business data, whether stored on internal systems or on cloud servers, is backed up and can be restored immediately in case of any unfortunate information loss incident. 

Your developers should be experts in implementing an effective backup and disaster recovery strategy to recover data. Your development team can work on a software-as-a-backup or website backup solution for this purpose. 

A few example data backup solution providers include Backupify – a SaaS solution and CodeGuard – a web disaster recovery solution.

  • Endpoint Security

With the increased use of IoT-powered devices, businesses have had to implement security systems for a number of interconnected smart devices. 

Just as Web Application Firewalls have become a necessity for cloud security, endpoint protection software is becoming crucial with the rising use of IoT infrastructure today.

By implementing a DNS, your cybersecurity developers can stop access to malicious and fraudulent websites and suspicious data entering your network through any connected device.

Another technique your developers can implement for endpoint security is managed detection and response (MDR). It is used to manage, detect, and respond to all cyber threats across all connected devices. 

MDR monitors all devices and alerts users when there is abnormal behavior shown by any of them.

Lastly, your developers should be skilled in persistence detection. This refers to a cyber attack situation, where hackers enter a system and wait for the right opportunity to attack the vulnerable network. 

Persistence detection looks for intruders by collecting information and activities associated with persistent network processes.

To ensure effective endpoint security, your developers should be familiar with solutions like Cisco Umbrella for DNS, SentinelOne for MDR, and Huntress for persistence detection.

  • Network Monitoring

Monitoring is a necessary component of any cybersecurity tech stack as it enables oversight of an organization’s network in the search for vulnerabilities. 

You developers can look out for vulnerable computing resources with security tools like security information and event management (SIEM) and network detection and response (NDR).

A SIEM is an effective cybersecurity tool to monitor your network that allows integration with major technology platforms like Microsoft.

This monitoring tool will alert you of any unauthorized access, multiple failed login attempts, or any kind of anomalous data in your network traffic. 

The security information and event management tool places all the security threats and alerts in a centralized database for cybersecurity developers to investigate and deal with any risks efficiently.

Network Detection and Response is another effective network security and monitoring strategy. It is more focused on closely monitoring the network data packets.

Its network traffic analysis (NTA) approach helps in the timely detection and removal of anomalous data on your network.

Your developers should be familiar with software solutions like Perch and Qualys for SIEM, NDR, and vulnerability assessment and scanning.

Develop Cybersecurity Software Application

Your developers should have top-notch software development skills to build robust cybersecurity software. We are discussing some of these below:
