types of controls organizations
The objective of A.8.1 is to identify the data assets that are within the scope for the ISMS and to define protection responsibilities. Run a discovery to identify all information assets within your organization, such as paper records, digital files, removable devices and email. Then create an asset registry. For each asset, assign a data owner the responsibility of protecting it.
specifies the types of controls organizations need to implement in order to ensure accurate identification of information security assets, designate responsibility for security, and ensure data assets are protected based on their classification levels. The controls defined by the regulation that are divided into technical, organizational, legal, physical and human resource controls.
Note that ISO 27001 does not specify an exact list of sensitive assets; your organization makes that decision using its best judgment.
The annex is broken into three main subparts, which are described briefly below. Then we will take a deeper dive into the second subpart, which concerns data classification.

Critical Path Methodology (CPM)
The critical path is the sequence of activities whose sum of activity time is longer than that for any other path through the network
Critical Path Analysis is commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance.
Any project with interdependent activities can apply this method of mathematical analysis.
All project schedules have (at least) one critical path, usually only one in non-manipulated project schedules.
The critical path is important because if everything goes according to the schedule, their duration gives the shortest possible completion time for the overall project
Activities that are not in the critical path have slack time
Slack time – It is defined as the amount of time a task can be delayed without causing another task to be delayed or impacting the completion date of the overall project.
Activities on a critical path have zero slack time, and conversely, activities with zero slack time are on a critical path
When planning to add personnel to tasks imposing time constraints on the duration of a project, the project’s critical path should be revalidated first.
Here is a simple example of Critical path methodology:
The above picture represents a project. Let us say Project A. The stages of the project range from Stage 1 to Stage 11. There are different ways to complete the project, i.e., to reach stage 11. The numbers mentioned above the arrow marks represent the time taken to complete each task. Now, let’s calculate the time taken to complete the project’s task and the different ways to complete the project.
Path 1 = Stage 1 – 2 – 5 – 7 – Stage 11 = 3 + 2 + 3 + 7 = 15
Path 2 = Stage 1 – 3 – 4 – 6 – Stage 11 = 1 + 5 + 3 + 5 = 14
Path 3 = Stage 1 – 8 – 9 – 10 – Stage 11 = 7 + 3 + 2 + 1 = 13
Path 4 = Stage 1 – 3 – 4 – 9 – 10 – Stage 11 = 1 + 5 + 1 + 2 + 1 = 10
Now, the critical path is the longest route in completing the project. In such a case, in the above picture, path 1 is the longest route, which takes the maximum time to complete the project.

What is Information Management?
Information management is the practice of collecting, managing and distributing information. Data can be acquired from a wide range of sources, and can come in a variety of formats. Then it must be stored securely in an organized and structured way that both meets relevant regulations and policies and ensures it is accessible to authorized employees. Strong information governance is essential to effective information management.
Accordingly, more and more businesses are looking to transition from information management to knowledge management systems. But what exactly are the differences between knowledge management and information management? Are there any concepts and terms from information management that you can use to help your organization implement knowledge management effectively?
Data — no matter how secure and organizations — proves its worth only when it’s used to deliver value to the business. In other words, the bits and bytes must be turned into information in order to be useful intellectual capital. Enter knowledge management: the process of capturing, distributing and effectively using knowledge.
This definition might make knowledge management sound a lot like information management, but in this context, the word “knowledge” means a processed form of information that goes beyond merely extracting facts from collected data. Knowledge discovery focuses on the application of information: Knowledge creation is what happens when people refine information into something useful.

working and all the data restored
I ran the restore command again — with the right password — and it worked! Everything came back! My new instance had the same problem AND the same solution. By the end of the day, I had them both working and all the data restored
Crestfallen, the caller thanks our hero and ends the call … likely pondering his surely impending transfer to a radar station somewhere in the back end of Alaska.
Several months after this call, our hero did bravely pack up his personal belongings, tell his boss what he really thought of him, and leave, never to set foot in that office again. At that time, the customer was still sending people to each of their devices to insert a key, turn it to the Reset position, turn it back, and remove it — a process that took them nearly THREE years to complete for all of their devices
Luckily, the customer was hosted by us as a single tenant instead of a multi-tenant environment and we were able to limit the damage to a single server but that server was holding the database as well. Even though we had to pay damages for not keeping up 99.99%, the fact that we resored everything back to normal was the biggest saving grace.

SQL Server logins and server roles
Permissions are the types of access granted to specific securables. At the server level, permissions are assigned to SQL Server logins and server roles. At the database level, they are assigned to database users and database roles.
You have three main ways to control permissions:
Grant — The GRANT statement enables principals to access specified securables.
Deny — The DENY statement prevents principals from accessing specified securables.
Revoke — The REVOKE statement eliminates permissions that were previously granted for specific securables.
Note that the DENY permissions statement overrides all granted permissions.
Securables are organized into a hierarchy comprised of servers, databases, schemas, and objects contained within those schemas. Permissions can be assigned at the server, database, schema or single object level.
Note that permissions granted at a higher level of the hierarchy automatically apply to lower levels, unless you specifically deny them to the securable’s children and grandchildren objects.
