Learn to extract five-tuple data—source and destination IPs and ports, plus the transport protocol—from network events using Wireshark and firewall logs to correlate connections and investigate suspicious activity.

Compare rule-based (signature-based) detection triggered by known threats with behavioral (statistical) detection that flags unusual activity, as shown by Firepower Management Center and Stealthwatch.

Perform attack surface analysis to identify entry points and data paths, enabling developers and security professionals to test high-risk areas and re-evaluate the application.

Explore network attacks, from reconnaissance with nmap and Sparta in Kali Linux to DoS and man-in-the-middle threats, with prevention like dhcp snooping and dynamic arp inspection.

Explore attacker evasion methods, including encryption and tunneling with VPNs, traffic fragmentation, protocol manipulation, and pivoting, illustrated by a lab demo of a slow loris attack exhausting server resources.

Learn how network logs from routers, switches, and firewalls help security investigations and troubleshooting, with event severity levels, time synchronization via a.p. servers, and external logging for auditing.

Explore packet captures to retrieve raw IP traffic data for troubleshooting and security investigations using tcpdump and Wireshark. See how display filters and encryption protect credentials like telnet sessions.

Explore netflow as a security monitoring backbone, collecting flow data from devices to reveal anomalies, correlate events, and drill into exfiltration alarms to identify and remove risky hosts and users.

Explore next-gen firewall events on Cisco firepower devices managed by firepower management centers, view IPX events in intrusions and events, and use the context explorer for readable graphical security data.

Explore how encryption protects network communication by converting plaintext to ciphertext with symmetric and asymmetric keys, and learn about ciphers such as substitution, polyalphabetic, and transposition, hashing for data integrity.

Implement public key infrastructure (pki) by generating csrs and signing them through certificate authorities to issue identity certificates that enable authentication and encryption for web servers, vpns, and trusted devices.

Explore Windows processes and threads, learn how to use Sysinternals Process Explorer to drill into application activity, and examine the registry, WMI, handles, and services as potential attack vectors.

Explore Linux as an open source operating system used in platforms and compare it with Windows on price, reliability, and security. Install Kali Linux and use the terminal.

Explore the Linux XFS file system, its journaling for data integrity, the bootloader and master boot records, and how data and swap partitions—with swap as a forensic source—support operation.

Explore how sandboxing isolates apps from secure resources to test software and study malicious behavior; Cisco amp analyzes files in a sandbox, while per-tab processes protect browsers.
