Initial foothold No hardening effort should come at the expense of upgrading operating systems. Use AppLocker to block exec content from running in user locations home dir, profile path, temp, etc. Hardening against DMA Attacks?

Deploy security tooling that monitors for suspicious behavior. Office files that support macros docm, xlsm, pptm, etc. Ensure these file types are blocked. Limit workstation to workstation communication. Increase security on sensitive GPO s. Evaluate deployment of behavior analytics Microsoft ATA. BloodHound "prevention": Use NetCease to prevent unprivileged session enumeration. Use Samri10 to prevent unprivileged local admin collection this fix already exists in Windows 10 and above.

This will clear credentials of logged off users after 30 seconds mimicking the behavior of Windows 8. This will prevent Wdigest credentials being stored in memory, again as is the default for Windows 8. Limit workstation to workstation communication Windows Firewall.

Enforce LDAP signing.Hardening refers to providing various means of protection in a computer system. Protection is provided in various layers and is often referred to as defense in depth. Protecting in layers means to protect at the host level, the application level, the operating system level, the user level, the physical level and all the sublevels in between. Each level requires a unique method of security. Hardening activities for a computer system can include:. Toggle navigation Menu. Home Dictionary Tags Security.

For more information, see Investigate connection events that occur behind forward proxies. If you're using Transparent proxy or WPAD in your network topology, you don't need special configuration settings. Configure a registry-based static proxy to allow only Microsoft Defender ATP sensor to report diagnostic data and communicate with Microsoft Defender ATP services if a computer is not be permitted to connect to the Internet. Configure the proxy:. If a proxy or firewall is blocking all traffic by default and allowing only specific domains through, add the domains listed below to the allowed domains list.

URLs that include v20 in them are only needed if you have Windows 10 machines running version or later. For example, us-v If a proxy or firewall is blocking anonymous traffic, as Microsoft Defender ATP sensor is connecting from system context, make sure anonymous traffic is permitted in the previously listed URLs.

The information below list the proxy and firewall configuration information required to communicate with Log Analytics agent often referred to as Microsoft Monitoring Agent for the previous versions of Windows such as Windows 7 SP1, Windows 8. If your network devices don't support the URLs added to an "allow" list in the prior section, you can use the following information. As a cloud-based solution, the IP range can change.

It's recommended you move to DNS resolving setting. Right-click Command prompt and select Run as administrator. For example:. If at least one of the connectivity options returns a status, then the Microsoft Defender ATP client can communicate with the tested URL properly using this connectivity method.

Note settings-win.Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal called the "case" at the surface.

For iron or steel with low carbon content, which has poor to no hardenability of its own, the case-hardening process involves infusing additional carbon or nitrogen into the surface layer. Case-hardening is usually done after the part has been formed into its final shape, but can also be done to increase the hardening element content of bars to be used in a pattern welding or similar process.

The term Face hardening is also used to describe this technique, when discussing modern armour. Hardening is desirable for metal components that are subject to sliding contact with hard or abrasive materials, as the hardened metal is more resistant to surface wear. However, because hardened metal is usually more brittle than softer metal, through-hardening that is, hardening the metal uniformly throughout the piece is not always a suitable choice.

In such circumstances, case-hardening can produce a component that will not fracture because of the soft core that can absorb stresses without crackingbut also provides adequate wear resistance on the hardened surface.

Early iron smelting made use of bloomeries which produced two layers of metal: one with a very low carbon content which is worked into wrought ironand one with a high carbon outer layer. Since the high carbon iron is hot shortmeaning it fractures and crumbles when forgedit was not useful without more smelting.

As a result, it went largely unused in the west until the popularization of the finery forge.

Case-hardening involves packing the low-carbon iron within a substance high in carbon, then heating this pack to encourage carbon migration into the surface of the iron. This forms a thin surface layer of higher carbon steel, with the carbon content gradually decreasing deeper from the surface. The resulting product combines much of the toughness of a low-carbon steel core, with the hardness and wear resistance of the outer high-carbon steel. The traditional method of applying the carbon to the surface of the iron involved packing the iron in a mixture of ground bone and charcoal or a combination of leatherhoovessalt and urineall inside a well-sealed box.

This carburizing package is then heated to a high temperature but still under the melting point of the iron and left at that temperature for a length of time.

The longer the package is held at the high temperature, the deeper the carbon will diffuse into the surface. Different depths of hardening are desirable for different purposes: sharp tools need deep hardening to allow grinding and resharpening without exposing the soft core, while machine parts like gears might need only shallow hardening for increased wear resistance. The resulting case-hardened part may show distinct surface discoloration, if the carbon material is mixed organic matter as described above.

The steel darkens significantly, and shows a mottled pattern of black, blue, and purple caused by the various compounds formed from impurities in the bone and charcoal. This oxide surface works similarly to bluingproviding a degree of corrosion resistance, as well as an attractive finish.

Case colouring refers to this pattern and is commonly encountered as a decorative finish on firearms. Case-hardened steel combines extreme hardness and extreme toughness, something which is not readily matched by homogeneous alloys since hard steel alone tends to be brittle.

Carbon itself is solid at case-hardening temperatures and so is immobile. Transport to the surface of the steel was as gaseous carbon monoxidegenerated by the breakdown of the carburising compound and the oxygen packed into the sealed box. This takes place with pure carbon but too slowly to be workable. Although oxygen is required for this process it is re-circulated through the CO cycle and so can be carried out inside a sealed box. The sealing is necessary to stop the CO either leaking out or being oxidised to CO 2 by excess outside air.

Although bone was used, the main carbon donor was hoof and horn. Bone contains some carbonates but is mainly calcium phosphate as hydroxylapatite. This does not have the beneficial effect of encouraging CO production and it can also introduce phosphorus as an impurity into the steel alloy. Both carbon and alloy steels are suitable for case-hardening; typically mild steels are used, with low carbon content, usually less than 0.

These mild steels are not normally hardenable due to the low quantity of carbon, so the surface of the steel is chemically altered to increase the hardenability.

The term case-hardening is derived from the practicalities of the carburization process itself, which is essentially the same as the ancient process. The steel work piece is placed inside a case packed tight with a carbon-based case-hardening compound.

This is collectively known as a carburizing pack. The pack is put inside a hot furnace for a variable length of time. Time and temperature determines how deep into the surface the hardening extends.Active Directory Security.

Oct 21 Securing workstations against modern threats is challenging. The best way to create a secure Windows workstation is to download the Microsoft Security Compliance Manager currently at version 4. Review the options, change as needed, and export as a GPO Backup folder. Then apply this newly created GPO to your workstations. This will improve your workstation security baseline if you have minimal security settings already configured, especially if you have no existing workstation GPO.

Note that these locations are subject to change with further updates. This post covers many of these as well as other good security practices and configuration. Obviously, you should move to the most recent version of Windows and rapidly deploy security patches when they are available.

The following items are recommended for deploying a secure Windows workstation baseline, though test first since some of these may break things. Deploy current version of EMET with recommended software settings.

Disable WPAD. Disable Windows Browser Protocol. Deploy security back-port patch KB Prevent local Administrator RID accounts from authenticating over the network. Ensure WDigest is disabled. Microsoft AppLocker provides out of the box application whitelisting capability for Windows. It is highly recommended to use AppLocker to lock down what can be executed on Windows workstations and servers that require high levels of security. AppLocker can be used to limit application execution to specific approved applications.

There are several difference phases I recommend for AppLocker:. Expected Impact: This is likely to break things in the enterprise, please test first.Given, this machine is also for personal use, so I am looking to balance convenience against security and privacy in the event of loss or theft.

I also thought of some anti-theft protection such as Prey Project. Ok, You have convinced me: BItLocker universal it will be. I will report back once I have set the startup policy and enabled it. Thanks very much. I did google but all I could find is the non-tpm configuration. Seems to be working well and will test hibernation recovery at some stage.

When encrypting the C drive it'll ask you to reboot, and the process will start after you next log in. Other drives will start encrypting immediately, that might explain the missing progress dialog. Chris' suggestion is not something I've mentioned. This is unrelated, but are there any plans to move Windows 10 S to this kind of model by default?

The current advice plastered all over S though is that users take the free upgrade to Pro so they can run non-store programs; wouldn't it be more beneficial to provide users with a lightweight VM to run such "untrusted" software? Be aware that if you need to elevate unsigned executables you will have set "Only elevate executables that are signed and validated" to "Disabled", otherwise you will receive the " A referral was returned from the server. Hardening of your machine should rely on the Least Privilege principle.

Use a non admin account for daily use. Disabling un-used programs, services and firewall rules. Minimizing your attack surface and turning off un-used network facing Windows features. While I applaud MS for improving protection on kernel things, attackers do not have to necessarily touch the kernel to do damage.

I have seen damages to Windows Defender and Windows Edge, just as an example. And their improvements rest on having new hardware, which leaves countless older platforms unprotected. Also their new innovations also relies on Windows Server Active Directory, which no home user has. And sometimes, even when MS has been notified of working exploits, they fail to make changes to their code. These MS techs only know to expound on their latest innovations.

They are not incident responders. And they do not know how to harden Windows. However, I do agree that BitLocker is the way to go since the thread starter's main concern is theft or lost laptop. Kaspersky has Online connection to their threat center.
