U11 Summary
U11 is about learning the various methods that are used to infiltrate computer systems and how these attacks are prevented. To know about these attacks fully, it is important to also know what makes them possible.
another part of U11 is learning how to prepare countermeasures to various attacks and deciding which is the most effective. -
Aim 1
aim 1 is to know about the various parts of the unit, being able to describe them.
to reach this, it will be important to understand all of the units lessons, and complete the tests after to know what to focus on. -
Aim 2
to reach aim 2 it is important to be able to use the knowledge that was needed in aim 1, this means that it will be important to understand the unit instead of just remembering it.
to reach the understanding needed it will be important to experience virtual scenarios that will help with knowing what to use where. -
Aim 3
to reach this aim it is important to know how to analyze data. this means that it will be important to look at scenarios where data needs to be analyzed and observe the methods used carefully.
it will also be important to attempt to analyze data to get experience with it. -
Aim 4
to reach aim 4 it is important to be able to evaluate the various methods of security and justify the decision. this requires knowledge of the various differences between the different methods of combating attacks, and the different types of attack. -
Aim 5
aim 5 is about being able to keep a network secure and deal with security issues as they happen, explaining the reasons for the actions.
this will be the most difficult, as it requires the largest range of knowledge including all of the knowledge required in the previous aims.
it will also be vital to practice this, as it will be easy to make mistakes. -

practice exam notes
Exam:
-revise internal threats (Topic 1)
-revise external threats (Topic 2)
-revise system vulnerabilities (Topic 4)
-practice laying out the activities
-time needs to be spent reading everything
-notes need to be made
-every small detail is useful
-I need to ensure that I can complete all of the prompts in a detailed way, as they follow on from each other
-I need to practice managing the time for the different tasks -
last lesson
last lesson we:
-looked over a past exam paper
-attempted to complete some of the work from the paper
-listed everything that I needed to focus on
-planned to look into the areas that required attention -
this lesson
this lesson we learned about:
-lab
}
-the importance of hashing in verifying file integrity
-the importance of keeping track of which website is being visited, preventing hacking attempts from succeeding
{
-past paper
{
-what another of the past papers is about
-which themes of the exam papers are constant and which change
-what I need to revise to be capable of completing it
} -
last lesson
last lesson i:
Facts:
{
-learned about the importance of file integrity
-learned about how websites can be made with malicious intent
}
Emotion:
{
-this topic is easy to understand
}
Benefit:
{
-i will be better at understanding file security
}
Ideas:
{
-i could think of more ways to avoid malicious websites
}
Planning:
{
-i will look at the lab again today, ensuring that everything that i missed is completed
}
Judgement:
{
-some of the facts about file integrity can be difficult to understand
} -
this lesson
this lesson i:
Facts:
{
-configured different types of wireless security
-researched issues with wireless security
}
Emotion:
{
-I think that this interesting
}
Benefit:
{
-this will help me to further understand how to secure wireless networks
}
Ideas:
{
