Non-compliance is a concept that should send a chill down the spine of any product leader. It can lead to genuinely company-ending ramifications. In 2023, the EU fined Meta $1.3 billion for disregarding General Data Protection Regulation (GDPR) compliance. The Federal Trade Commission (FTC) and the Department of Health and Human Services (HHS, the US government agency overseeing HIPAA) are now cracking down on compliance breaches.

Yet, our 2024 State of Software Quality survey showed that only 49.51% of teams implement secure coding standards, and only 42.48% are using Static Application Security Testing tools that will identify compliance concerns. These results suggest product leaders still aren’t taking security seriously. Maybe these leaders think compliance isn’t a priority for them. 

They would be wrong. If you are using, storing, or transmitting personal information, there will be regulations you must comply with. Failing to do so can result in severe financial penalties, legal consequences, and reputational damage.

The Incredible Importance of Compliance 

Up to June 2024, companies worldwide have been fined $4.5 billion for violating GDPR, with annual fines increasing. And it's not just about the money; a single compliance breach can erode customer trust, tarnish a company's reputation, and even lead to criminal charges.

The stakes are only getting higher. As data breaches and cyber-attacks become more frequent and sophisticated, governments and regulatory bodies ramp up their enforcement efforts. In the United States, the FTC imposed a record-breaking $5 billion fine on Meta in 2019 for privacy violations. HIPAA penalties reach up to $16 million per violation.

But compliance isn't just about avoiding penalties; it's also about protecting your customers and your business. A study by IBM found that the average cost of a data breach in 2022 was $4.35 million, the highest they had ever recorded. Food company Mondelez underperformed the market by 15% over the following three years after their data breach. In other words, non-compliance doesn't just hurt your bottom line—it can threaten your very existence.

As a product leader, you are responsible for prioritizing compliance and embedding it into every aspect of your software development lifecycle. This means implementing secure coding practices, using automated compliance tools, conducting regular audits, and fostering a culture of security awareness among your team. Only by taking a proactive and comprehensive approach to compliance can you mitigate risks, maintain customer trust, and ensure the long-term success of your product in an increasingly regulated world.

The Huge Challenges of Compliance

Saying all that is easy. Doing so is a lot harder. Let’s briefly break down each of these secure and compliant coding components.

Secure Coding Practices

Implementing secure coding practices is the foundation of compliance. This involves adopting a secure software development life cycle (SDLC) that integrates security at every stage, from design to deployment. Developers should follow the OWASP Secure Coding Practices, which provide input validation, authentication, authorization, session management, error handling, and more guidelines. Additionally, teams should perform regular code reviews, using techniques like pair programming and peer review to catch potential vulnerabilities early in development.

However, implementing secure coding practices can be challenging, especially for teams with tight deadlines and limited resources. It requires a significant investment in training and tools and a shift in mindset from focusing solely on functionality to prioritizing security. Moreover, as new threats emerge and regulations evolve, teams must continuously update their practices to stay compliant.

Automated Compliance Tools

Automated compliance tools, such as Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST), can help teams identify vulnerabilities and compliance issues in their codebase. SAST tools analyze the source code without executing it, using data flow analysis and pattern-matching techniques to detect potential security flaws. On the other hand, DAST tools test the application in runtime, simulating attacks to identify vulnerabilities that may not be apparent in the source code.

While these tools can be invaluable for catching compliance issues early, they also have limitations. False positives are common, requiring manual review and triage by security experts. Moreover, these tools can be expensive and complex to set up and maintain, requiring specialized knowledge and resources.

Security Audits

Regular security audits and risk assessments are essential for evaluating a product's compliance posture and identifying areas for improvement. These audits should cover both technical and procedural security aspects, including code reviews, penetration testing, access controls, incident response plans, and more. Depending on the level of assurance required, audits can be conducted internally or by third-party security firms.

However, audits can be time-consuming and resource-intensive, requiring significant planning and coordination across multiple teams. They can also disrupt the development process, as teams may need to pause work to address audit findings. Moreover, audits are only a point-in-time assessment, and teams must continually monitor and improve their security posture to stay compliant.

Security Culture

Perhaps the most challenging aspect of compliance is fostering a culture of security awareness among the development team. This involves educating developers on the importance of security, providing them with the tools and resources they need to write secure code, and incentivizing them to prioritize security in their work. It also means breaking down silos between development and security teams, encouraging collaboration and communication throughout the SDLC.

Building a strong security and quality culture requires leadership buy-in and ongoing investment in training and awareness programs. It also requires a shift in mindset from viewing security as a hindrance to recognizing it as a critical enabler of business success. Only by embedding security into the very fabric of the organization can teams truly achieve and maintain compliance in the long term.

Easy Compliance With Codacy

Security is a core strength of Codacy. That’s because we see security as integral to code quality. Secure code is quality code, and high-quality code is inherently secure. 

Let’s show this in practice. First, we use a simple example of a few insecure coding practices that can lead to compliance problems. Here’s some quick code for a Python app that allows a user to register, login, and view their profile:

from flask import Flask, request, session, redirect, render_template
import sqlite3

app = Flask(__name__)
app.secret_key = 'insecure_secret_key'

# Initialize the database
def init_db():
    conn = sqlite3.connect('users.db')
    c = conn.cursor()
    c.execute('''CREATE TABLE IF NOT EXISTS users
                 (id INTEGER PRIMARY KEY AUTOINCREMENT,
                 username TEXT NOT NULL,
                 password TEXT NOT NULL,
                 email TEXT NOT NULL);''')
    conn.commit()
    conn.close()

# User registration
@app.route('/register', methods=['GET', 'POST'])
def register():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']
        email = request.form['email']

        conn = sqlite3.connect('users.db')
        c = conn.cursor()
        c.execute("INSERT INTO users (username, password, email) VALUES (?, ?, ?)", (username, password, email))
        conn.commit()
        conn.close()

        session['username'] = username
        return redirect('/profile')

    return render_template('register.html')

# User login
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        username = request.form['username']
        password = request.form['password']

        conn = sqlite3.connect('users.db')
        c = conn.cursor()
        c.execute("SELECT * FROM users WHERE username = ? AND password = ?", (username, password))
        user = c.fetchone()
        conn.close()

        if user:
            session['username'] = username
            return redirect('/profile')
        else:
            return "Invalid username or password"

    return render_template('login.html')

# User profile
@app.route('/profile')
def profile():
    if 'username' in session:
        username = session['username']
        conn = sqlite3.connect('users.db')
        c = conn.cursor()
        c.execute("SELECT * FROM users WHERE username = ?", (username,))
        user = c.fetchone()
        conn.close()

        if user:
            return render_template('profile.html', user=user)
        else:
            return "User not found"
    else:
        return redirect('/login')

if __name__ == '__main__':
    init_db()
    app.run()

What are some security issues within this code? Let’s ask Codacy. If we connect the repo with this code to Codacy, we can see the issues that arise in the security and risk management dashboard:

Under the hood, Codacy leverages a wide range of static code analysis tools to detect security vulnerabilities across multiple languages and platforms. These include industry-standard tools like Semgrep, Bandit, and ESLint, as well as Codacy's analysis engine. By aggregating findings from multiple tools into a single platform, Codacy provides comprehensive coverage and reduces the risk of false negatives.

Codacy has highlighted three concerning elements of our code: two critical fixes and one medium. We can dive deeper into each problem by clicking on the details:

Nice. We can see that this can introduce an SQL injection attack into our system. It also gives us two possible fixes: parameterized queries and ORMs. It also tells us the likely time to fix it so we can add this to our backlog.

This is a toy example, but Codacy runs on every PR. Your team can catch these insecure inconsistencies with every code change before they hit production. How does this help each of the four challenges above?

  • Secure coding practices: Codacy helps enforce secure coding practices by automatically detecting vulnerabilities and providing actionable guidance on fixing them. This enables developers to learn and implement best practices for secure coding throughout the development lifecycle.

  • Automated compliance tools: Codacy acts as a single-point compliance tool, integrating security flaws, compliance issues, and quality concerns from an entire suite of SAST tools. It uses these static code analysis techniques to identify potential problems early in the development process, reducing the risk of compliance breaches.

  • Security audits: Codacy simplifies the process by providing a centralized dashboard highlighting security risks and compliance issues. This allows teams to quickly assess their security posture and prioritize areas for improvement, making audits more efficient and effective.

  • Security culture: By integrating security checks into the development workflow, Codacy helps foster a culture of security awareness among developers. It provides developers with immediate feedback on security issues, encouraging them to prioritize security in their work and collaborate with security teams to address vulnerabilities.

For more sophisticated use cases, Codacy helps organizations identify, track, and address security issues across their entire codebase. This feature automatically opens time-bound, prioritized findings whenever security problems are detected in your organization's repositories, connected Jira instances, or as a result of penetration testing.

The Security and Risk Management overview page provides a high-level view of your organization's security posture:

codacy security and risk management dashboard

This includes key metrics such as the total number of open findings, the distribution of findings by severity, the history of finding resolution, and a breakdown of the most high-risk repositories and most detected security categories. Product leaders can use this information to quickly assess their organization's overall security posture, identify areas for improvement, and track progress over time.

In addition to detecting vulnerabilities, Codacy also categorizes findings into common security categories such as SQL Injection, Cross-Site Scripting (XSS), and Insecure Storage. This helps teams quickly identify patterns and prioritize remediation efforts based on the most prevalent issues in their codebase.

By providing a centralized platform for managing security findings across the entire software development lifecycle, Codacy allows organizations to proactively identify and address security risks before attackers can exploit them. This helps teams maintain compliance with relevant regulations and standards and fosters a culture of security awareness and accountability throughout the organization. If your organization needs help with security and compliance, you can sign up for Codacy to understand any issues with your current codebase, or reach out to us to discuss your security needs and ensure your organization is 100% compliant with any regulatory requirements.
