Why is Using Two-Factor Authentication critical for Cyber Security in San Antonio?

San Antonio cyber securityIf you want to make sure your San Antonio cyber security protects your business and confidentiality, you need to constantly assess its viability. Due to the uptick in cybercrime in recent years, it’s crucial to use multi-factor authentication. In other words, you need more than just a password to login to an account.

The Second Factor

The purpose of a second factor for authentication is that it adds an extra layer of security. Since hacking software exists that can eventually hack any password, it’s more secure to add at least a second factor that must be identified by the user, such as a PIN number or an answer to a question. The idea is that it’s too much trouble for even algorithmic-driven software to figure out.

It’s important that your San Antonio cyber security is a combination of your careful use of digital networks and technology that uses multiple layers of barriers that discourage cyber criminals. The second factor often involves the following:

  • ATM card
  • Phone number
  • Zip code
  • Voiceprint
  • Fingerprint
  • Time
  • Location
  • Other forms of established ID

Even though the second factor can be breached by a hacker, the extra layer of security is safer than without it. Many hackers are turned away by the complexity, as they prefer easier targets. The three factors that tend to define a second authentication are knowledge, cards or other possessions and biometrics such as fingerprints. A more advanced technology is called behavioral biometrics, which includes analysis of speech patterns.

Implementing 2FA

Once you decide to shift to a 2FA login policy, you must choose a method that will be seamless for your company, whether the system is new or an upgrade. One way to deploy a new 2FA policy is through a smartphone app. It can also involve tokens or RFID cards. Products that facilitate two-factor authentication based on tokens or smart cards used for logging in are designed to recognize authorized users. Keep in mind that security tokens can be hacked.

One of the reasons to implement a 2FA policy is if your company saves money by allowing a bring-your-own-device (BYOD) workforce. The 2FA policy works well with smartphones and can be done numerous ways. Some companies use facial recognition or iris scanning software, along with a microphone to detect voice recognition.

So far, 2FA has been widely successful at guarding against database breaches and phishing campaigns. Eventually, hackers usually figure out how to penetrate deeper, so it raises the question of how long 2FA will be effective. The National Institute of Standards and Technology (NIST) has warned that SMS in 2FA services is vulnerable to attacks due to mobile phone number portability.

At some point, you must think beyond 2FA since there are even more security layers to consider. Three typical types of hacks are driven by brute-force, dictionary or rainbow table software. These programs are designed to breach password-driven systems but have limited capabilities.


Since most attacks come from remote locations, second authentication makes it difficult for hackers to penetrate systems.
