cyber security dos and don’ts during covid 19. Cyber Security has been a matter of concern for the organisations from a long time and on top of it Covid-19 brought lot of challenges to attain the same.
The COVID-19 situation has compelled organisations and individuals to take up security measures like social distancing and remote working. Governments and civil administration are bringing up new ways to ensure that their citizens would remain hopeful and stable. New economic plans, relief packages have been announced by the government.

Attackers are targeting businesses as well as individuals by downloading ransomware disguised as legitimate applications.
Managing Cyber Security has become more challenging in the Work from Home scenario. Following are the Do’s and Don’t for employees and individuals.
CYBERSECURITY DOS DURING COVI19
- Use hard-to-guess passwords or passphrases. A password should have a minimum of 8 characters using uppercase letters, lowercase letters, numbers and special characters.
- Create an acronym. An acronym is easy for you to remember but hard for anhacker attacker to guess. For example, pick a phrase that is meaningful to you, such as “My dad’s birthday is 12 December, 1975.” Using that phrase as your guide, you might use Mdbi12/Dec,75 for your password.
- DO change your password in a regular interval, within every 30 days. This will make difficult for the hacker to use your cracked password.
- DO use different passwords for different accounts. If one password gets compromised, your other accounts are still safe.
- DO pay attention to the mails you receive, phishing traps in email and watch for tell-tale signs of a scam. DON’T open mail or attachments from an untrusted source. Whenever you receive a suspicious email, the best thing to do is to delete the message, and report it to your manager and Chief Information Security Officer (CISO)/designated security representative.
- DO change your default username and password of your Wi-Fi router, remember that wireless is inherently insecure. Avoid using public Wi-Fi hotspots. Use your organisation provided virtual private network software to protect the data and the device.
- Always keep your system updates, install the updates pushed by your organisation
- DO keep your passwords or passphrases confidential. Never share your passwords with others or write them down. You are responsible for all activities associated with your credentials.
- DO place confidential paper at proper places at home and destruct it properly prior to putting in dustbin.
- DO destroy information properly eg. by shreddinga, when it is no longer needed.
- Always backup your critical data to the drives and location provided by your IT Team
- Never turn off antivirus system installed on your PC and keep it updated.
- DO avoid printing confidential information outside personal printers. Always be aware of your surroundings when printing, copying, faxing or discussing sensitive information
- DO keep your work devices are either shut down or locked—including any mobile phones you use to check email or make work phone calls.
- DO report all cyber incidents and suspicious activity to your reporting manager and CISO/designated security representative.
CYBERSECURITY DONTS DURING COVI19

Always use privacy settings on social media sites to restrict access to your personal information. In a nutshell avoid sharing too much personal information on social media.
