10 Key Principles of Software Engineering Security
Software needs a comprehensive security strategy. This includes various layers of protection to ensure your system is safe from threats. Look into the key principles regarding software engineering security to keep your digital assets safe.
1. Confidentiality
It ensures high confidentiality by making sensitive information available only to authorized viewers. This is a very important principle in ensuring private data is not infiltrated or compromised.
Some of the important practices to uphold confidentiality in security for software include encryption methods, access controls, and secure communication channels.
2. Integrity
Integrity refers to the principle under which data remains valid and intact throughout its entire processing. This ensures that information remains unchanged, intact, and reliable from the time it is created until it is destroyed.
Hashing, checksums, and digital signatures are among the other common techniques implemented in support of data integrity and for detecting changes unauthorized by an organization.
3. Availability
The tenet of availability ensures that at any time, all information or resources become accessible to an authorized entity. This tenet is fundamental in ensuring that a system or data is always up and usable when needed.
Strategies to enhance availability include redundancy, failover mechanisms, and routine maintenance.
4. Authentication
Authentication verifies users, devices, or systems before granting access. This principle establishes a foundation of trust and guarantees that no unwanted entity has any access. Some common modes of authentication include passwords, biometrics, and multi-factor authentication, which involves more than one factor.
5. Authorization
Authorization ensures that proper access to resources is either granted or denied based on user roles and their permissions. This allows users to perform certain actions and view data strictly within their scope of responsibility. RBAC and ABAC are highly applied authorization models.
Here’s a quick comparison of both models.
| Model | Description |
| RBAC (Role-Based Access Control) |
|
| ABAC (Attribute-Based Access Control) |
|
6. Non-Repudiation
Non-repudiation, meaning the assurance that events and transactions cannot be denied after they have occurred, ensures accountability and legal compliance. This aspect is crucial for proving the origin and integrity of data. Digital signatures and audit logs are tools that assist in non-repudiation.
7. Accountability
It maintains a record of user activities in a log, which supports monitoring and auditing security-relevant actions. This principle is very instrumental in detecting and effectively responding to security incidents.
Compliance with organizational policies or regulatory requirements is also possible via this principle. Detailed logging and monitoring systems make accountability possible.
8. Security by Design
Security by Design refers to the philosophy whereby considerations of security are integrated right at the beginning into the software development life cycle.
It represents a proactive way of ensuring that security features form an integral part of the design and development process. This also includes threat modeling, secure coding standards, and security testing, among others.
9. Least Privilege
This ensures that you have only the least possible set of privileges that enable you to perform your tasks. After that, the possibility that the privileges will be misused, either by accident or intention, is diminished. The principle of least privilege is maintained through periodic review and updating of access rights.
10. Robust Defense
Software engineering security in depth refers to the exercise of multiple layers of security controls against different forms of threats. This principle seeks to provide complete security through the combination of physical, technical, and administrative controls in place.
Examples may include firewalls, intrusion detection systems, and security policies sanded up as defenses.
Integrating Security into the Software Development Life Cycle (SDLC)
Skipping security in the software development life cycle means leaving your applications open. It is about integrating security right from the word go, just like the state-of-the-art security system before laying the foundation.
Security implemented at every phase of the SDLC, from planning to design, development, testing, and deployment, constructs a truly resilient defense against cyber threats. These practices are injected into all phases not only to protect your software but to make it reliable against newly emerging threats.
