Here, we are describing some assessment tasks. These are:

Assessment Task 1: Identify appropriate security for digital devices

When it comes to protecting digital devices, there are a variety of security measures that can be taken. The most important thing is to understand the risks and vulnerabilities associated with each device and to choose the appropriate security measures based on those risks.

Some common security measures for digital devices include:

  • Password protection
  • Firewalls
  • Antivirus software
  • Data encryption

Each of these measures has its own strengths and weaknesses, and it is important to choose the right ones for each device based on its specific risks. For example, password protection is a good way to protect devices from unauthorized access, but it is not very effective against attacks that can circumvent the password requirement. On the other hand, antivirus software can protect against some types of attacks, but not all of them.

1. Create and maintain a register of digital devices on the organizationā€™s network

Another important security measure is to create and maintain a register of all the digital devices that are connected to the network. This should include information about where each device was purchased, how it is used within the organization, who is responsible for its maintenance, etc.

It can be useful to map out which devices are affected by which risks according to their location. For example, if an office worker connects their home laptop to the network (which may be at risk of various attacks), then that laptop should be registered in the same way as any other device on the network. However, it is not necessary to register every single digital device in the world, such as devices at homes outside of the organization.

2. Confirm what information is held on the registered devices

Once a register of digital devices has been created, it is important to confirm what information is held on each device. This includes both the confidential and non-confidential information that is stored on the device.

It is also important to ensure that the information on the device is up-to-date. This can be done by regularly scanning devices for updated information. It is also a good idea to delete any information that is no longer needed on digital devices, such as old documents and pictures, so that there is less risk of confidential information being leaked if the device falls into the wrong hands.

3. Categorize the level of risk associated with each device based on the sensitivity of information stored

Finally, it is important to categorize the level of risk associated with each device based on the sensitivity of the information stored. This can help to determine which security measures are most appropriate for each device.

For example, devices that store highly sensitive information should be given a higher priority than devices that store less sensitive information. And, within each category, devices that store sensitive information should be given higher priority than those that do not.

4. Select the required security protocol to manage the level of risk associated with each device

Once the level of risk associated with each device has been determined, it is important to select a security protocol to manage those risks. In practice, this can be done by choosing the security measures that have been discussed previously.

However, it is also important to keep in mind that there are other types of security protocols beyond those that have already been discussed. For example, there are security protocols that can be used to manage digital devices themselves (such as requiring certain authentication before using the device), and there are security protocols that can be used for data transmission over a network (such as SSL or HTTPS).

Assessment Task 2: Apply protection strategies to digital devices

There are a number of different protection strategies that can be applied to digital devices. In this section, we will discuss some of the most common ones.

Password protection

One of the most basic forms of protection is password protection. This can be used to protect devices from unauthorized access or to protect information on the device from being accessed by unauthorized users.

Generally, password protection is implemented by requiring the user to enter a password before they can access the device or its information. This password can be specific to the device, or it can be the same password that is used to access other devices or information.

Device encryption

Devices can also be encrypted. In practice, this means that the device itself is protected from unauthorized access by encrypting all of the information stored on it. If a device is encrypted, then any unauthorized user who tries to access the device will only see gibberish instead of actual content. This makes unauthorized access much more difficult.

There are two main types of device encryption: hardware-based and software-based. Hardware-based encryption protects the device in such a way that it can only be accessed by certain components of the device (such as CPU, RAM, etc.). Software-based encryption uses software to encrypt all of the information stored on the device.

Data loss prevention (DLP)

Data loss prevention (DLP) software can be used to monitor all data transmitted from a device. In practice, this means that the DLP software will only allow certain types of information to be transmitted from the device, and it will block other types of information. This helps to prevent unauthorized access to sensitive information.

There are a number of different DLP software products on the market, and each one has its own features and capabilities. It is important to select a product that meets the specific needs of your organization.

Antivirus software

Another common form of protection is antivirus software. This software can be used to protect devices from being infected with viruses or other malware.

Antivirus software is available for a variety of different platforms, including Windows, Mac, and Android. It is important to select a product that meets the specific needs of your organization.

Firewall

A firewall is a software or hardware device that can be used to protect devices from being accessed by unauthorized users over the network. A firewall can be used to protect a single device, or it can be used to protect an entire network.

Firewalls are available for a variety of different platforms, including Windows, Mac, and Android. It is important to select a product that meets the specific needs of your organization.

1. Install and run the latest anti-malware on each device

It is important to install and run the latest anti-malware on each device. This will help to protect the device from being infected with viruses or other malware.

Anti-malware software is available for a variety of different platforms, including Windows, Mac, and Android. It is important to select a product that meets the specific needs of your organization.

2. Create strong passwords across personal and work accounts

It is important to create strong passwords across personal and work accounts. If a password is too easy for unauthorized people to guess, then they will be able to access both the account and all of its contents (which may include sensitive information).

Creating strong passwords involves using passwords that are at least 8 characters in length. However, it also involves making sure that the password includes a variety of different characters, including uppercase letters, lowercase letters, numbers, and symbols.

It is also important to never use the same password for multiple accounts. If one account is compromised, then the attacker will be able to access all of your other accounts as well.

3. Switch on two-factor authentication where available

It is important to switch on two-factor authentication where available. Two-factor authentication will ensure that whoever tries to access an account must have both the correct password as well as a separate piece of information (like a code generated by another device).

4. Encrypt devices according to instructions

It is important to ensure that devices are always encrypted according to instructions. Encrypting a device will help to protect the operating system and all of its contents (which may include sensitive information) if the device is lost or stolen.

There are several different ways in which you can encrypt your devices, including software-based encryption, hardware-based encryption, and whole-disk encryption.

It is important to follow the instructions carefully when encrypting a device. If you do not encrypt the device properly, then it may be possible for an attacker to access all of its contents (which may include sensitive information).

5. Develop an associated physical security plan and communicate this to the whole organization

It is important to develop an associated physical security plan and communicate it to the whole organization. This should include a variety of different steps, such as only accessing the office when other people are also present, storing valuable items in a secure location, and maybe purchasing a shredder for confidential documents.

Physical security is an important part of information security. By taking a few simple steps, you can help to protect your organization from physical attacks that may attempt to steal or damage devices or data.

It is important to remember that information security is not just about protecting devices and data from being accessed by unauthorized people. It is also about protecting the devices and data from being damaged or lost.

The final section in this guide will cover a variety of different tips that can help protect devices and data from being damaged or lost.

Assessment Task 3: Evaluate the effectiveness of applied protection strategies

After taking the necessary steps to protect your devices and data, it is important to evaluate the effectiveness of these protection strategies. This will help you to determine if any additional steps need to be taken, or if the current protection strategies are working as intended.

One way to evaluate the effectiveness of protection strategies is to perform a security assessment. A security assessment will allow you to determine exactly how vulnerable your organization is to security incidents. It can also help you to identify the most important information assets that need to be protected, as well as any potential areas of weakness.

Having a strong relationship with one or more external security companies may be beneficial for organizations looking to conduct a comprehensive internal security assessment. These companies can help to identify potential vulnerabilities and provide recommendations for how to fix them.

Another way to evaluate the effectiveness of protection strategies is to monitor the number of security incidents that occur. This will give you an idea of how effective your protection strategies are in preventing attacks from occurring.

If the number of security incidents increases over a particular time period, then it is a sign that your protection strategies may be lacking. This indicates the need for new security measures to be put in place or existing ones to be improved upon.

It is also important to verify compliance with security standards and industry best practices. Non-compliance with industry standards can have serious ramifications on an organization’s brand and reputation.

Organizations should also consider implementing a risk management program. This will allow you to identify, assess, and manage the risks associated with using information technology. By doing so, you can help to ensure that the benefits of using information technology outweigh the risks.

If you are unsure about how well your protection strategies are working, it might be beneficial to hire a third party to conduct an external security assessment. This will provide you with a completely independent point of view, as well as recommendations for how to improve your protection strategies and prevent future incidents from occurring.

Finally, it is important to consider the results affecting end-users. If your current protection strategies are not working or are inconvenient for end-users, they will likely find ways to circumvent them. This can leave your organization vulnerable to security incidents.

By taking the necessary steps to protect your devices and data, and then evaluating the effectiveness of these protection strategies, you can help to ensure that your organization is safe from potential security threats.

1. Review the number of breaches and business impact over the review period

The number of security incidents has been on the rise in recent years, and this is reflected in the number of data breaches that have occurred. In 2016, there were 1,093 data breaches that affected more than 176 million records. The following year, the number of data breaches increased to 1,632, and the number of records affected jumped to more than 1.3 billion.

It is important to note that not all security incidents result in data breaches. However, the number of data breaches that have occurred in recent years is a clear indication that organizations are not doing enough to protect their data.

The business impact of these data breaches can be significant. In 2017, the number of records breached totaled 191 million, and the estimated total cost of these data breaches was $2.13 billion. Furthermore, in 2018 there were almost 90% more records breached than the previous year, which demonstrates that cybercrime is on the rise.

2. Monitor latest developments in digital security

Since data breaches and cyber attacks appear to be increasing in frequency, it is important to stay up-to-date on the latest information about cybersecurity. You can do so by monitoring recent developments in digital security.

For example, if you want to stay informed about threats related to ransomware, you should follow new announcements from law enforcement agencies. By doing so, you can learn more about the latest ransomware attacks and how to protect yourself against future threats.

By regularly monitoring the latest digital security developments, you can stay informed of potential vulnerabilities in your current protection strategies. This will help to ensure that your organization is safe from new cyber threats.

3. Support organizations to select the most appropriate security strategies

Many organizations find it difficult to select the most appropriate security strategies for their needs. This is often because there are so many different options available, and it can be difficult to know which ones are the most effective.

Organizations can overcome this challenge by working with a third-party security provider. This provider can help you to identify the best protection strategies for your needs, as well as provide support for any changes that may be necessary.

Additionally, it is important to consider the potential business impact of each protection strategy. For example, if you are only looking at implementing one security measure, then this will likely have a larger impact on end-users than perhaps several smaller measures. As there are often concerns about potential negative business impacts, you should first ensure that your selected protection strategies will not impact the productivity of end-users.

By implementing the appropriate security measures and regularly monitoring them for effectiveness, you can help to ensure that your organization’s data is safe from cyber-attacks and other vulnerabilities. This will also increase the likelihood that future security incidents won’t result in a major data breach.

Assessment Task 4: Patch software across multiple devices

It is important to keep all software up-to-date, as this helps to reduce the risk of cyberattacks. One way that you can do this is by patching software across multiple devices.

To patch software across multiple devices, you need to first identify all of the devices that are in use within your organization. You can do this by gathering information from all departments.

Once you have a complete list of devices, you should prioritize them depending on the level of risk each device poses to your organization. For example, if a networked printer has been connected to your office network but is not being used very often, it might be wise to deprioritize this device.

On the other hand, devices that are used frequently should be prioritized higher. For example, laptops used by employees might need to be patched more regularly than printers because they are likely to have a greater number of security vulnerabilities.

When you have identified which devices should be prioritized for patching, you can then implement your chosen strategy for deploying patches. For example, you might choose to automatically patch devices with low priority, whereas other devices would require manual updates.

1. Apply updates to software and applications across own desktop and mobile devices

Organizations can benefit from regularly patching software with updates, as this helps to reduce the risk of potential security vulnerabilities. To do so, you can implement your chosen updates strategy across all desktop and mobile devices.

For example, you might choose to automatically deploy any required patches after they have been approved by an administrator or senior technical person within your organization. This will help to ensure that all devices are updated in a timely manner.

Alternatively, you might choose to deploy updates on a voluntary basis, with the option for employees to install them whenever they have time. This can be helpful for devices that are not always connected to the network, such as laptops or tablets.

You should also consider how you will deploy updates to different types of software. For example, updates for desktop applications might need to be deployed differently than updates for mobile apps.

By implementing a regular patching schedule and using the appropriate updates strategy, you can help to reduce the risk of cyberattacks and other security vulnerabilities. This will also increase the resilience of your organization’s IT infrastructure.

2. Ensure that new devices are updated and configured correctly as part of the initial start-up procedure

When a new device is connected to a network, it should be updated and configured correctly before being connected to the production environment. This should be done as part of the initial start-up procedure for each device.

To ensure that devices are updated correctly, you can implement your chosen updates strategy across all devices that connect to your organization’s IT infrastructure.

For example, you might choose to automatically deploy any required patches or updates after they have been approved by an administrator or senior technical person within your organization. Alternatively, you might choose to wait until devices are connected to the production environment before deploying these updates.

You should also consider how new devices will be configured when they are first connected to your network. For example, you might choose to automatically configure devices with the correct settings and permissions after they have been updated.

By implementing a process for updating and configuring new devices, you can help to protect your organization’s IT infrastructure from potential security threats.
