Implement essential wireless security measures and tools to protect networks, including device inventory, AP and antenna placement, rogue AP detection, and strong encryption (WPA3/WPA2) with NAC.
Plan, design, and secure an IoT solution with device management, network monitoring, data processing, and encryption.
Explore how cryptography hides information and protects data with symmetric and asymmetric encryption, key escrow, and digital signatures for secure online communication.
Explore how encryption algorithms transform plaintext into ciphertext and compare des, aes, rc4, rc5, and rc6, including rsa and dsa for digital signatures and public-key security.
Learn how PKI uses public and private keys, digital certificates, and certificate authorities to enable secure, authenticated, and non-repudiable electronic communication through encryption and digital signatures.
Explore file, removable media, and disk encryption, including AES and public key methods, and learn about keys, recovery plans, and best practices for protecting data.
Explore data backup and restore to protect against loss. Compare tape, disk, direct to cloud, cloud to cloud, and SaaS backups, and learn retention policies and Bcdr for rapid recovery.
Examine raid levels and their data redundancy, performance, and capacity trade-offs, from raid zero to raid ten, and learn how SNIA standards shape data formats.
Learn how data loss occurs and how data loss prevention (DLP) detects breaches and prevents leakage across endpoints, networks, and cloud, using identification, monitoring, and file security like Imperva.
Implement and configure the snort intrusion prevention and detection system on a linux based system, covering updates, dependencies, and compilation steps using yum, wget, tar, and make.
Install and configure snort on linux and ubuntu, update ldconfig, create unprivileged users and directories, set permissions, and prepare white, black, and local rules with community rules.
Configure snort for ids/ips by editing snort.conf, setting the home net and rule paths, and enabling local and community rules, then test and monitor alerts in snort.log.
Configure time zone using localization settings and enable NTP synchronization on a firewalld system; create and enable a swap file with fallocate, set proper permissions, and auto-start at boot.
Install and configure OpenVPN on CentOS seven, set up the OpenVPN access server via the official repo, create user Rudy, and connect using the client interface on Windows.
