Securing Your Mobile Devices
Information security systems for computers have been around for some time, but with the wide usage of mobile devices, we are now concerned about their security as well. Security mechanisms need to be carried out on these devices because we are using them to store more sensitive and valuable information.
Some security systems are simple to implement, while others are a little more technical. According to the Department of Defense, Northrup Grumman, the three largest challenges with mobile security “are how to certify the security, how to protect the information in a wireless mode, and how to protect data at rest”. So, we need to address these challenges by carrying out effective security systems to protect not only the mobile device itself, but also data that are stored on the device. Some of these security mechanisms include User Authentication, Mobile Device Encryption, Data Security Restrictions, Jail breaking Restrictions, Mobile Device Configuration, Installation of Anti-Viruses and Updates, Digital Certificates and finally Physically Security.
User Authentication
Setting up user authentication on your mobile device will restrict unauthorized users from gaining access to your information. This method implements a requirement for users to enter their username and password before gaining access the device.
Mobile Device Encryption
Mobile device encryption involves the use of an encryption system that encrypts and protects the data from unwarranted attacks and infiltration. This method is considered by many experts as the best way to protect sensitive data. The best encryption system is one that protects the entire disk or full disk. This means both data and hardware is protected.
Data Security Restrictions
Implementing restrictions on sensitive and important information is another security mechanism that is very effective. It protects data, through restrictions of checking account information, social security numbers, and credit card information from appearing on mobile devices.
“Do not Jailbreak”
One of the least adhered to security risk is jailbreak. A jail broken phone is a gateway for Malware and other types of malicious attacks and invasions. Also, exposing your phone to unwanted attacks and bugs will cause your phone to get seriously get messed.
Mobile Device Configuration
When your mobile device is not using connections such as Wi-Fi, Bluetooth or Infrared, they should be disabled. In addition, Bluetooth connections should be set to “undiscoverable” so they are unable to detect by unauthenticated devices.
Install Anti-virus and Updates
It is recommended by US-CERT to install anti-virus software to update signatures and search engines. In addition, perform regular updates and download bug fixes as they become available.
Digital Certificate
Digital certificates, also called public key (PK) certificate, pretty much verify the individual that owns the public key. For instance, if you want to send a message, you would need to provide the recipient with an encoded key to prove to the recipient who you are. A Certificate Authority (CA) usually provides these digital certificates.
Physical Security
One best way to secure your mobile device is to minimize theft as well as use tracking software. By simply never leaving your phone unattended, backing up your data on a regular basis and implement locks, will minimize data and phone loss. Tracking software such as Computrace and MobileMe are reliable for tracking your device. This is if it gets lost or stolen.
A security system on your mobile device should not be an option, but necessary. Due to the escalation of Cybercrime, it is necessary to secure confidential information from potential hackers, Malware and possible system malfunction.
