1. Traditional security measures

   • Data Encryption
     • Data encryption or file encryption is a procedure whereby files, or any type of document, become completely illegible thanks to an algorithm that messes up its components.
   • Digital signature
     • A digital signature is a cryptographic mechanism that allows the recipient of a digitally signed message to identify the originator of that message and confirm that the message has not been altered since it was signed by the originator.

2. Levels of security models

   • Level 1: Operational System
     • Level 2: Communications
       • Level 3: Data Storage
         • Level 4: Application Environment

3. Security protocols

   • WEB
     • It is the encryption system included in the IEEE 802.11 standard as a protocol for Wireless networks that allows encryption of the information transmitted.
   • WPA
     • It emerged to correct the limitations of the WEP. It introduced security improvements such as the TKIP (Temporal Key Integrity Protocol), which varies by itself the Wi-Fi password from time to time.
   • WPA2
     • It is the most modern standard for protecting wireless networks and the one recommended by the Wi-Fi Alliance. There is also a personal (WPA2-Personal) and business (WPA2-Enterprise) version.

4. Security implementation

   • Encrypt / Decrypt
     • Encryption is the process with which we encrypt a text and make it something unintelligible to some other system
     • To decrypt consist in the process of taking an encrypted text and we convert it into a understandable text.
   • AES algorithm y CryptoJS
     • The AES (Advanced Encryption Standard) algorithm is one of the most popular for encrypting information because it was designed to be optimal in hardaware and software

5. Mobile device security is the full protection of data on portable devices and the network connected to the devices. Common portable devices within a network include smartphones, tablets, and personal computers.

6. Components of mobile device security

   • Endpoint security
   • VPN
   • Secure web gateway
   • Email security broker
