Building and Designing Secure Software

“One that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards is the only really safe system.” gene spafford

Although the following Gene Spafford quotation could make you laugh, it really emphasizes the everyday crucial difficulty you have: maintaining the security of your software in a digital environment growing in complexity.

Dealing with the complexity of secure software development as a CTO of a SME is about building trust and guaranteeing the survival and profitability of your company, not only about protecting data.

The knowledge and best practices this blog offers will help you create safe software, reduce risk, and protect your company. Let’s get right into it.

Value of Security in Computer Programming
We live in a digital economy, hence security is not just a feature but also a basic corporate enabler. Apart from significant financial losses, a single hack may permanently harm your reputation. This is the reason incorporating security into the core fabric of your software development process is not optional but necessary.

Recognizing the hazards
Within the field of software development, you run many hazards that can jeopardize the integrity, security, or operation of your programs. Here is a closer view of the typical weaknesses and hazards you, the CTO, have to be alert of:

Online attack


Cyberattacks now happen more often and are really destructive. For example, the 2017 WannaCry ransomware assault crippled hospitals, banks, and companies by affecting about 200,000 systems spread over 150 countries. This attack underlined the terrible consequences of security flaws in generally used systems.

More recently, the supply chain attack known as the SolarWinds hack in 2020 compromised thousands of companies worldwide, including government institutions, therefore exposing the broad ramifications of security vulnerabilities in network management software.

Recovering from a ransomware assault can be time-consuming and expensive, upsetting your business processes and maybe tarnishing your brand.

Embedded Systems Weaknesses
The Internet of Things (IoT)’s development has added still another level of complication. These days, smart appliances including thermostats, security cameras, even vehicles are linked to the internet. One weakness in a single device could serve as a gateway, allowing a possible attack to reach your whole network.

Because of their frequently extended use and difficulties in regular update, embedded systems are routinely attacked.

Dependent Systems Interactions


Software ecosystems of today are hardly stand-alone entities. They interact both inside and outside of other systems quite a lot. Should one system have a security flaw, it can be taken advantage of to provide access to other linked systems, therefore setting off a domino effect.

A weakness in a supplier’s system, for example, can disclose your own information.

Software Complexity and Scope
Managing and safeguarding software systems gets more challenging as they get in scale and complexity. Many times featuring more lines of code, large systems can have more faults and possible security flaws.

A typical situation involves sophisticated modern business solutions, such ERP systems, which can be difficult to safeguard because of the great volume of data they handle and the several connection points they involve.

Outsourced Software Supply Chain Risks


Outsourcing software development carries hazards, especially if the supply chain is not closely controlled. The already mentioned SolarWinds incident is a perfect illustration of how supply chain weaknesses may be taken advantage of to get illegal access to data and sensitive systems. Reducing these threats depends on thorough screening, ongoing observation, and strong security systems.

Getting Attacks More Sophisticated
Cybercriminals are always improving their tools and approaches. Rising trends are complex phishing tactics that replicate genuine requests and polymorphic malware, which may modify its code to elude detection. Emphasizing improved detection tools and proactive threat hunting, these changing strategies demand a dynamic approach to cybersecurity.

Leveraging Legacy Software


Many companies still depend on legacy systems that might not be supported with security upgrades or fixes, therefore exposing themselves to vulnerabilities.

Attributed to a weakness in the Apache Struts framework, a component of their legacy systems, the Equifax data hack in 2017 exposed personal information of almost 147 million consumers. This breach made clear the terrible results of neglecting to keep and upgrade software components.

Being a software development firm, Codewave is aware of the need of including security at every stage of the software development process to make sure your digital assets stay safe and the integrity of your company stays whole.

Typical Security Software Engineering Problems
Crucially, one must clearly grasp the security risks hiding in the shadows. But equally crucial is spotting the weaknesses that might find their way into your program during development.

Some typical safe software engineering problems you should be aware of are broken out here:

Third-Party Library and Framework Vulnerabilities


Third-party components can be a two-edged blade. Although they enable speedier development and ease of use, they can also bring unanticipated security hazards.

Older libraries with known flaws or malicious code buried inside them can expose your program. This is how one may reduce this risk:

Third-Party Codes for Veterines thoroughly: Never just copy any library you come across. Investigate the reputation of the library, look for known flaws, and keep a current inventory of outside components your project uses.
Remain current. Right away apply security patches to outside libraries. Think about making use of actively kept libraries with solid security records.
Attack by Injections
Untrusted data given to an interpreter as part of a command or query causes injection flaws—SQL, NoSQL, LDAP, etc. These weaknesses might let attackers access or corrupt your data, therefore causing major security lapses.

Always validate and sanitize inputs to help to reduce these risks; also, utilize prepared statements or parameterized searches in your database access practices.

Authorized Insecurity and Verification


One of the main security hazards are insufficient access restrictions. Unauthorized individuals may easily get into your systems and data by means of weak passwords, insufficient multi-factor authentication, and inappropriate access control techniques. Following these security recommended practices can help you:

Apply minimum password length criteria, complexity guidelines, and consistent password resetting.
MFA, or multi-factor authentication, requires a second verification element—a code from your phone—in addition to a password, therefore augmenting the security level.
Use role-based access control (RBAC): Grant users access just the tools and information required to do their jobs. Steer clear of allowing everyone administrative access.
XSS attacks—cross-site scripting—have attackers introducing harmful scripts into online pages seen by other users, therefore leveraging weaknesses in certain web applications. These attacks might cause session tokens, stolen cookies, or even website defacing.

Content security policies, validating and escaping user inputs, and leveraging safe frameworks that automatically manage these risks can help to drastically lower XSS risk.

Challenges of Mobile Application Security


Development of mobile applications has own security issues. Here are a few areas you should give great thought:

Store sensitive data—such as credit card information or passwords—not on the device itself but rather securely elsewhere. Guard data at rest and in transit using safe encryption methods.
Inadequate Application Rights: Usually, mobile apps ask different rights to operate. Examine closely the permissions your app requests and steer clear of giving unwarranted access.
weaknesses in cloud security


Securing data and apps in the cloud becomes more difficult as your activities grow out into this space. Although they provide strong security measures, cloud platforms need careful setup and monitoring.

Stress safe access policies, data encryption, and frequent security audits to help to reduce cloud computing related hazards.

Starting with a strong basis in safe software engineering techniques, a fundamental idea of Codewave, helps one avoid security traps. Our development teams are ready to find and fix these weaknesses so safeguarding your software environment.

Safe Software Development Architecture


After establishing the scene with the kinds of risks and weaknesses you encounter, let’s now discuss how you could practically protect your initiatives.

The Secure Software Development Framework (SSDF) provides a strong road map for include security all through your development process. This framework is proactive rather than merely a list of rules; it’s a means of laying a safe basis for any software project.
