All You Need To Know About Cybersecurity - Dr Nizar Ben Neji

You Should Know:

Cybersecurity is a critical field that protects systems, networks, and data from digital attacks. Below are some essential commands and practices to enhance your cybersecurity skills:

1. Linux Commands for Cybersecurity:

nmap: Scan networks for open ports and services.
```
nmap -sP 192.168.1.0/24
```
tcpdump: Capture and analyze network traffic.
```
tcpdump -i eth0 -w capture.pcap
```

iptables: Configure firewall rules.

iptables -A INPUT -p tcp --dport 22 -j ACCEPT

chkrootkit: Check for rootkits on your system.
```
sudo chkrootkit
```

2. Windows Commands for Cybersecurity:

netstat: Display active connections and listening ports.
```
netstat -an
```
tasklist: List running processes.
```
tasklist /svc
```
sfc: Scan and repair system files.
```
sfc /scannow
```
netsh: Configure network settings and firewall.
```
netsh advfirewall set allprofiles state on
```

3. Cybersecurity Tools:

Wireshark: Analyze network protocols.
Metasploit: Penetration testing framework.
Burp Suite: Web vulnerability scanner.

4. Best Practices:

Regularly update software and systems.
Use strong, unique passwords and enable multi-factor authentication (MFA).

Encrypt sensitive data using tools like GPG.

gpg --encrypt --recipient '[email protected]' file.txt
