Linux Unified Key Setup, or LUKS [luhks] as it will be referred to as from here on out, is a widely used method of disk-encryption. LUKS is proprietary to the Linux Kernel and a device encrypted with LUKS will not mount in a Windows or Apple environment. LUKS can encrypt entire block devices such as Hard Disks Drives (HDD), Solid-State Devices (SSD) such as USB sticks or Flash drives, partitions, etc. LUKS is largely recommended for protecting removable storage media, laptop hard-disks or Linux swap files and not recommended for file level encryption.

Malware Types Malware can be classified by it’s behavior, target platform, or attack commands. Of the three classifications, we will look more specifically at malware based on behavior. These can be divided into 8 different categories:
- I. Infectors

Course Overview I recently completed and was awarded my
SANS GCIA Certification. The GCIA or GIAC Intrusion Analyst certification is a course that focuses on learning how to configure intrusion detection systems (Snort, Bro, SiLK) and analyze logs, and network traffic. I took the six day boot camp that was taught by Mike Poor.
In an attempt to stay motivated and focus on my own individual projects while I’m not at work. I’m going to challenge myself to post more frequently in a blog-esqe style. Tutorials and technical write-ups will still come. I’m primarily using this as my own motivational tool. SANS Holiday Read more…
RAM stands for Random-Access Memory and is commonly referred to as RAM or Memory for short. It serves as temporary storage and working space for the operating system and its applications. This allows data to be accessed (read or written) in almost real-time regardless of the physical location inside the memory as opposed to HDDs, Disc Drives, or any other mechanical media. In the majority of computers, RAM is an easily upgradeable option that will increase the performance of your operating system and application usage. RAM is a volatile type of storage medium. Which means if you reboot, shutdown, or have a power loss of any sort, every bit of data residing in memory no longer exists.
