Who should lead a security team Should the approach to security be more managerial or technical?
Ideally, the lead of a security team should have some technical background, but it isn't essential. A good manager is one who listens to what other team members are saying and is able to make decisions based on the evidence. The manager must rely on the technical expertise of the members, even if they themselves are also technical in nature.
For a security team it is usually the case where a senior technical lead becomes the manager after a period of time. That would be the best case scenario, but as mentioned, you have to have a person with good management skills overall, whether they are technical in the area or not.
A balanced approach is the goal from this team. The end results are technical, but the decisions and how the team operates come from management, and how they interface with the rest of the corporation is very important.

Why is RAID 0 not an option for data protection and high availability?
RAID 0 is data striping. This means that data will appear to a user as one logical disk but all the data is distributed among two physical disks. If one disk fails operation cannot continue and data is lost.
RAID 1 uses two disks that are mirrored copies of each other. If one disk fails, operation can continue and no data is lost.
What is a firewall access control list?
A control list of your firewall that you can access.
answer #2
--------------
an access control list is a set of rules that are compared to each incoming or outgoing packet or access to determine if they are allowed to pass. The rules have different formats depending on the manufacture but they do the same thing. For example a rule may say drop all packets to port external port 155, or drop all web requests from the inside to a particular web site. In a properly configured firewall all traffic is blocked unless it matches a specific rule, this prevents an application (like a virus) using an oddball port to communicate and download more dangerous software. When a new virus is discovered one way to prevent its spread is publicize the ports it uses so they can be at least monitored if not blocked entirely.
How do you set up a site to site vpn?

Business intelligence (BI) is an essential component to a successful governance, risk and compliance (GRC) strategy: It involves what I refer to as risk and regulatory intelligence. Basically, business has to monitor its internal environment -- as well as the external environment the company operates in -- for issues, events and risks that can impact the organization. The goal is be intelligent to maximize opportunities while mitigating or avoiding negative events.
In the business intelligence (BI) security domain to which you refer, this means implementing tools that have the ability to integrate into your environment to monitor changes, collect information, and report on the state of security across systems, processes and relationships. Further, these tools need to have content and process/workflow management capabilities to store information and provide processes to evaluate risk.
