Power Up Your Dev Career: Cybersecurity Skills That Set You Apart

Excited to speak at #PeakIT007! For this conference, I take a step back into my web developer years when I was the annoying colleague that brought a bit of cybersecurity into everyone’s life. I want to share that experience for any developer that wants a career boost. The title of the talk is “Power Up Your Dev Career: Cybersecurity Skills That Set You Apart” and it will be about the career advantages of knowing and applying cybersecurity in a development role.

You Should Know:

To help you get started with integrating cybersecurity into your development workflow, here are some practical steps, commands, and code snippets:

1. Secure Coding Practices

Input Validation: Always validate and sanitize user inputs to prevent SQL injection and XSS attacks.
```
import re
def sanitize_input(user_input):
return re.sub(r'[^a-zA-Z0-9]', '', user_input)
```

Use Prepared Statements: When working with databases, use prepared statements to avoid SQL injection.

String query = "SELECT * FROM users WHERE username = ?";
PreparedStatement pstmt = connection.prepareStatement(query);
pstmt.setString(1, username);
ResultSet rs = pstmt.executeQuery();

2. Linux Security Commands

Check for Open Ports: Use `nmap` to scan for open ports on your server.
```
sudo nmap -sT -O localhost
```
Audit File Permissions: Ensure sensitive files have the correct permissions.
```
sudo find / -type f -perm -o+w
```
Monitor Logs: Regularly check system logs for suspicious activity.
```
sudo tail -f /var/log/syslog
```

3. Windows Security Commands

Check for Open Ports: Use `netstat` to monitor network connections.
```
netstat -an | find "LISTENING"
```
Enable Firewall: Ensure the Windows Firewall is active.
```
netsh advfirewall set allprofiles state on
```
Check for Updates: Regularly update your system to patch vulnerabilities.
```
wuauclt /detectnow
```

4. Secure Your AWS Environment

Enable CloudTrail Logging: Ensure all API calls are logged.

aws cloudtrail create-trail --name MyTrail --s3-bucket-name my-bucket

Use IAM Roles: Assign minimal permissions to IAM roles.

aws iam create-role --role-name MyRole --assume-role-policy-document file://trust-policy.json

Encrypt S3 Buckets: Enable server-side encryption for S3 buckets.

aws s3api put-bucket-encryption --bucket my-bucket --server-side-encryption-configuration '{"Rules": [{"ApplyServerSideEncryptionByDefault": {"SSEAlgorithm": "AES256"}}]}'

What Undercode Say:

Cybersecurity is no longer optional for developers. By integrating security practices into your workflow, you not only protect your applications but also enhance your career prospects. Start with secure coding, regularly audit your systems, and leverage tools like nmap, netstat, and AWS security features to stay ahead. Remember, a secure developer is a valuable developer.
