Being a CISO of a publicly traded company is an extremely important job. Many shareholders invest their money and energy in publicly traded companies. If a CISO does not do their job properly, their company can lose millions of investments from their shareholders. The first protection that I would implement would be to encrypt data. I would make sure data is encrypted so people who should not have access to my companies data cannot get access to it. If they got access to this data, sensitive information can be stolen and it could give my company a bad reputation of being untrustworthy with valuable sensitive data. Another protection I would use would be to regularly update my companies system software. I believe updating system software is vital because if bugs occur and there is a quick and efficient update to fix it, it shows responsibility and protection to limit the spread of possible bugs. Also, if hackers are attempting to access and authorize sensitive information, their ability to will drastically decrease if bugs are identified and met with a software update. The last protection I would consider would be to implement MFA. I believe implementing MFA is crucial since MFA acts as another layer to protect the vulnerable. It is important to have MFA because it can deter hackers from continuing to attempt there hack if they are continually met with roadblocks.
