Common (Sense) InfoSec Tips for Remote New Hires

As the entire world is bravely fighting the menace of COVID-19 pandemic, a majority of the global 

workforce is working from home. Companies are on-boarding new hires remotely which adds another 

set of challenges from an information security (or infosec) perspective.

 

There is a common saying in the infosec community i.e. Security is only as strong as its weakest link.

Employees are the greatest asset for any organization. As infosec is everyone's responsibility, 

employees have to play an active role in ensuring the company operates in a risk free environment in 

today’s testing times. Out of people, processes and technology, I find people to be the most 

vulnerable or weakest link. A significant amount of data breaches occur due to employees exposing 

sensitive data inadvertently. You can refer to the 2020 Insider Data Breach Survey for more insights. 

For organizations, it is now more imperative to ensure new hires are well versed with the infosec 

best practices from day one considering they will be working remotely. The basic idea behind this 

blog post is to cover common sense infosec best practices and guidelines for new employees that 

will join any organization remotely. 


I have divided these best practices in four major sections to keep things simple. The infosec guidelines 

listed in this post are very generic and may not cover all aspects for an organization but can be 

considered as a good reference point to start with.


Thanks for reading this post ! As usual, If you have any comment/feedback please feel free to share. 


Technical Security


This section highlights generic but impactful security best practices for new employees when 

dealing with internet access, hardware, software and network access: 


  • Periodically patch all systems/hardware which you own (Computer, Phone, Bare Metal Servers, 

    Cloud Instances etc)

  • Always keep your workstation locked when you are away 

  • Always use a secure wireless network for internet connectivity 

  • Always use the latest available version of VPN as provisioned by your company for network access

  • Never check any secrets or passwords in plain text in software version control systems such 

    as Git, Bitbucket etc

  • Ensure you have two factor authentication enabled for critical business applications or flows 

    such as Single Sign-On, Git etc 

  • Never trust any external USB drives or external storage devices on company hardware. They 

    might be infected with ransomware or malware. 

  • Use only authorized software, as specified in your company’s IT security policy for your day to 

    day work

  • Use privacy screens for your laptop webcams.


Password Security


Passwords form the first line of defense. These specific guidelines can go a long way in securing 

passwords for new hires:


  • Choose a complex, unique non guessable password for company specific accounts such as 

    Single Sign-On as per your company’s password policy

  • Periodically change your password. Best practice is to rotate every 3 months (or 90 days) 

  • Never store or write passwords in plain text for e.g. google doc 

  • Never disclose your password to anyone including family members 

  • Choose different password for company accounts vs personal accounts

  • Use a password manager (again as dictated by the infosec policy) to manage multiple passwords 

  • Immediately contact the IT Support team/Incident Response team to reset your password in 

    case your company account gets compromised. 


Data Security and Privacy


This section highlights very basic but extremely important data security and privacy best practices 

that will be helpful for new employees: 


  • Always classify data and accordingly provision access. For example, company’s internal news 

    like hiring policy can be accessible to all employees whereas confidential information like 

    trade secrets can only be accessible to select employees with necessary clearance level. 

  • Production data should always remain in production. Never clone or create a local copy of 

    this data on your laptop/google drive/cloud data buckets etc unless necessary and you have 

    proper approvals from various stakeholders along with business justification.

  • Always involve infosec and privacy teams whenever dealing with sensitive data such as  

    Personally Identifiable Information (PII), Payment Card Data etc

  • Never store or collect user data or unique identifiers without specific user consent. 

  • Always encrypt user data such as PII or payment card data in transit as well as at rest. 


General Security


This section highlights general security tips that new hires can apply in there day to day work life:


  • Never download or open attachments from untrusted email addresses or sources. 

    These attachments might be infected with malwares, ransomwares, trojan horses etc. 

  • Never click on arbitrary links or images from untrusted email this may lead to phishing scam.   

  • Never use your corporate email addresses for registering into social networking sites or 

    subscription services such as Facebook, LinkedIn, Instagram, News Feeds etc

  • Never share company specific internal employee updates/news on social networking/public 

    forums 

  • Never trust and click on SMS messages originating from untrusted cell phone numbers. This 

    could allow attackers to remotely compromise your phone

  • Never fall prey to or be a victim of fake news or phone calls.

  • Never disclose any personal information like SSN, Passwords etc to any anonymous callers. 

  • Ensure you are attending remote web meetings from a trusted place with good personal privacy.

Software Security Verses of Wisdom


Last week, I published my debut rhyme on Linkedin. I devoted this rhyme to all the security engineers across the globe who are constantly striving hard to protect there stakeholders information (Companies, Organizations, Customers, Employees) from bad actors.   

I did not had a working title in my mind at that time. But now I have one hence re-publishing the rhyme to make it more meaningful.

Title: Software Security Verses of Wisdom

Data is the new gold, 
Attack vectors are getting bold, 
Insecure software over cloud, 
Adversary can exfiltrate data out, 
Secure by design is the remedy, 
To protect user data and privacy, 
Reduce complexity by adhering to basics, 
Can go a long way in securing assets, 
This is just an honest piece of advice, 
You can simply ignore or become wise …
