Well said Mansi. Nice points about the impact of inaccurate data. Incorrect data or excessive repetitive data has a negative effect on the clients loyalty.

I agree with you Annamarie. Master data management becomes complex especially when the company grows through merger or acquisitions. Any merger will create a duplicate master data. Database administrator resolves this by a process called as deduplication which is a data compression technique for eliminating duplicate copies of repeating data. But…[Read more]

Rightly said Yang. Not only does it make it easier for hacker but also allows human errors to happen. For example like you said an employee having right to propriety data accidently deletes the file or shares it with outsider. This requires that the principle of least privilege be applied for each role. Only minimum rights needs to be given to…[Read more]

Limiting access to minimal level and ensuring the normal functioning of business with those privileges results in fewer security incidents, reduced support cost, simplified path to compliance,…[Read more]

Nice example Vu Do. Approvals for access is a great way to manage system users.
In my previous company, the access to imaging lab was limited and the access was provided to the IT Technicians by the executive manager only after a written mail communication was send with justification as to why one needed access. And this security measure was…[Read more]

Great post Ming Hu. I guess adaptability to change is the most important characteristics and is also the most difficult competency for a security professional. As technology keeps changing one must be always updated with latest technological changes to be able to make better decisions for the firm.
I also think the security professional should…[Read more]

Nice point Abhay. Of course good communication skills help in communicating the need for security through out the firm. Along with being observant, a security professional should be analytical.

1. What is segregation of duties and why is it a commonly used control? Give an example of two (e.g. IT) roles that should be segregated?

I agree that administrators will have more idea about the security protocols and will be able to suggest on better solutions as they are the one’s who directly work and handle day to day issues. Normally it is of practice that the technician/administrator will study the issue, number of occurrence, suggest resolution, But the decision for change…[Read more]

Good suggestions Paul.
But in this case I do not think that would be applicable for the following reasons:
1. Not all teams/projects work in the same period. That would mean the system admin will have to identify which team or which project requires what account for how much time. I do not think that this would come under the role of an AD…[Read more] -

If I had to choose whether to allow inbound traffic or outbound traffic I would go for outbound traffic (intranet to internet) for security reasons alone and block inbound traffic (internet to intranet). In most cases that we hear of data breach, we find that attackers come in on inbound connections rather than outbound.
Though there are cases…[Read more] -
