Security Controls - Preventive

Preventive What you are trying to do is prevent some form of security breach/incident. Change management: Making sure that there or no outages that were not planned. Being as I work as an IT administrator, it's easy to want to make changes on the fly. The first step in this process is to submit the change plan and get approval. These changes can be network configuration changes or changing to a more current operating system. We need to plan, test, and practice before attempting the changes to reduce the chances of downtime on a production network. Security awareness and training:   Make users aware of social engineering attacks, email, and social network best practices. Once the users are aware of the tactics a social engineer might use, the less chance of them being fooled into revealing the passwords. For example, Microsoft is not going to call you and ask for your password, which is a threat actor attempting to social engineer you. Disabling Accounts: Hav...

RAID (Redundant Array of Independent Disks)

RAID (Redundant Array of Independent Disks) RAID 0: RAID 0 provides no fault tolerance or redundancy. Requires a minimum of 2 disks. The information is spread across each drive (for example: as it fills one block then adds data to the next sequential block).  RAID 0 is striping with no parity. If one drive fails, all the information is lost, unless you have a backup of the data. This form of RAID is used for performance, multiple heads reading/writing at the same time. Both drives should be of the same size and speed. If you have two 320 GB drives, theoretically you would have 640 GB of storage space using this configuration.  RAID 0 is best used for video and audio streaming. It could also be used for something like a backup server. The actual backups are stored on other media than the system running the backup software.  RAID 1: RAID 1 requires 2 drives and is known as mirroring. The exact same data is written to both drives.
