Security Testing Services

Security testing aims at verifying 3 basic principles:

  • Confidentiality – protecting sensitive information from  unauthorized users
  • Integrity – protecting information from being tampered
  • Availability – providing access to information when needed

Security test case that is not designed around security triad i.e. CIA is not a valid security test.

What we do

Security experts at AFour Technologies employ Static Application Security Techniques (SAST) and Dynamic Application Security Testing (DAST) techniques to discover potential threats that can be targeted by malicious users.

Security testing covers the entire ecosystem of network, host, application and data and a comprehensive security report with severity ratings is provided.

Security Development Lifecycle Process Design

Threat Modeling

Threat modeling is a structured approach to identify, evaluate and mitigate the risks to the system.
Uses STRIDE security development model.

IAM

Applications grouped in Security Zones to restrict connections

Prevent root logins

Restrict DB access further from few hosts

Add redundancy of application servers for high availability

Provide temporary sudo privileges to few users

Lock down ports

Security groups – allow access to applications from pvt network or bastion hosts. Not from internet.

Host hardening

Leverage AMIs for regular security patch management

Backup data regularly to mitigate disasters

Repudiation
