Internet and Web Servers

Websites are hosted on computers called Web Servers. These servers use programs that accept requests from clients.

Examples of Web Servers:

  • IIS (Internet Information Server)
  • PWS (Personal Web Server)
  • WAMP (Windows + Apache + MySQL + PHP)
  • LAMP (Linux + Apache + MySQL + PHP)
  • XAMPP
  • Apache (.php)

OpenSSL: Symmetric Encryption Algorithms & Examples

Symmetric Encryption Algorithms with OpenSSL

Encrypt the file “fichero.txt” using the RC4 symmetric encryption algorithm

OpenSSL> rc4 -in c:\cifrado\fichero.txt -out c:\cifrado\cifrado.rc4
enter rc4 encryption password:
Verifying - enter rc4 encryption password:

Decrypt the previous file:

OpenSSL> rc4 -d -in c:\cifrado\cifrado.rc4 -out c:\cifrado\descifrado.txt
enter rc4 decrypt password:

DES

Encrypt:

OpenSSL> des -salt -in c:\csb.log -out c:\csb.bf.txt

Backup Job Configuration:

  • A Backup Administrator configures a copy job. Options include: One backup file per VM, or one backup file for all backup jobs.
  • A Backup Administrator has restored a VM. The recovery process should be: Migrate to production.
  • If a backup job is started while another is running, the backup job will fail immediately.
  • The most appropriate setting for backup jobs is to run continuously.
  • A Backup Administrator must perform a level of recovery.

Network Design, Security, and Backup Solutions

Network Design and Implementation

I like the final network design. I went over the physical plan with Don Carson last week.

UPS Placement

By the way, where are you placing the UPS? In the IT closet, with the fireproof safe.

Cabling: Cat 6 vs. Fiber Optic

Did you decide on Cat 6 or Cat 5e cable? Cat 6. Don Carson suggested fiber optic, too. Cat 6 is fine. Fiber optic is too expensive. Agreed. Cat 6 is the best cable with a good price.

Data Backup Strategy

Sara, I think we should keep backup tapes offsite.
