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)
- Apache Tomcat (Pages .jsp)
Server Types
- Local server (intranet): http://IP_servidor.internet or http://localhost
- Remote server (internet): http://www.dominio.xxx or http://IP_publica

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
enter des-cbc encryption password:

Oracle DBMS Architecture: Key Concepts
Init.ora Configuration
The init.ora file is an archive of initialization values used to start an Oracle instance and establish configurations. It uses default values to optimize performance and resource allocation. This file sets all the parameters for Oracle to function correctly. There will be as many configuration files as there are active instances in the information system.
Control Files
Control Files are a set of small, stable files responsible for maintaining the consistency of the other files

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.
