Online Security Measures Explained


We all know businesses should have sufficient security measures in place to keep their business and customer data safe online, but what does this mean exactly? We’re looking at 5 methods that can be used to secure your business by minimising breaches and keeping attacks at bay.


1. Access Control

Make sure that all data and services can only be accessed by authorised people, by:

  • controlling physical access to the premises, computers, servers and network
  • restricting access to unauthorised users by limiting access to data
  • restricting data that can be copied from the system and saved to storage devices
  • limiting the sending and receiving of certain types of email attachments

2. Passwords

Use of strong passwords to restrict access to software and sensitive information. All passwords should:

  • consist of a combination of capital and lower-case letters, numbers and symbols
  • be between eight and 12 characters long
  • not contain any personal data like names or dates of birth
  • be changed regularly, preferably every 90 days
  • never be used by multiple users, or to access multiple accounts
  • use two factor authentication

Create a password policy and invest in technology like scheduled password resets, in order to enforce security best practice in your business.


3. System updates and intrusion monitors

Perhaps one of the most important measures is to keep your software and operating systems up to date. System updates contain vital security upgrades that continuously protect against known bugs and vulnerabilities, while intrusion detectors can monitor system and network activity. If a potential security breach is detected, it can generate an alarm, such as an email alert.

4. Firewalls and data encryption

Firewalls act as gatekeepers between the internet and your computer and can be an effective barrier for certain viruses and malware. However, make sure that your firewall is configured professionally to ensure optimum efficiency.

Encryption converts data into code that can't be read without a password or decryption algorithm, so it protects information held on a computer or transmitted over a network.

5. Software application security and SSL

While physical, firewall and server security are all very important, another area to look at is the software you run in your business, especially if you’re receiving and storing any sensitive information, like customer and banking details.

SSL - which means secure socket layering ie, encryption; is the standard security measure which encrypts data while it is in transfer between a web server and a browser in an online communication. This is an effective protocol to prevent data from being intercepted during an online transaction/transfer.


At Jeri Ltd, our unique security measures ensure that our systems are not vulnerable to the most commonly-used hacking methods. We encrypt our code with ionCube - which can not be reverse-engineered - so any leaks of custom security procedures through exposing the code to industrial spies are prevented. As part of our unique custom security models we safeguard against code injection, and all passwords are encrypted for storage.

Remember that risk management is key to online security as it creates a necessary balance between security and functionality in a business. An efficient risk management strategy can secure software and data without slowing it down and losing functionality.

Finally, you and your employees are responsible for keeping your business, your customers and any relevant data secure. Ensure that everyone understands the relevant security policies and procedures, and continually provide the relevant awareness and training.
