9 Module Overview Overview of Data-Related Security Threats Securing Data with EFS Implementing and Managing BitLocker

10 Lesson 1: Overview of Data-Related Security Threats What Is Defense in Depth? Discussion: What Are the Common Data-Related Security Threats? Possible Mitigations for Common Data-Related Threats

11 What Is Defense in Depth? Defense in depth involves: Applying multiple layers of security Guarding against a malicious user that breaches one or more of your security layers while trying to access confidential data Applying additional security layers

12 Possible Mitigations for Common Data-Related Threats Common data security threats: Unauthorized user accessing information on a file share Unauthorized user accessing data from a lost or stolen USB drive Lost or stolen laptop that is storing confidential information User s protected content to unintended recipient inadvertently

13 Lesson 2: Securing Data with EFS What Is EFS? Common EFS Usage Scenarios How EFS Works How EFS Recovery Works Demonstration: Using EFS to Secure Data Enterprise Solutions for Managing EFS

14 What Is EFS? EFS is a built-in file encryption tool for Windows: Enables transparent file encryption and decryption Provides for encrypted file recovery Allows encrypted files to be shared with other users

15 Common EFS Usage Scenarios Common usage scenarios for EFS: Protecting files on shared computers Protecting files from access by privileged users Limiting file access to specific users

16 How EFS Works How EFS works: EFS encryption occurs at the file-system level If a user attempts to open a file and possesses the necessary key, the file opens If a user does not possess the key, he or she receives an access-denied message EFS-encrypted files do not remain encrypted during transport if you save them to, or open them from, a folder on a remote server The file is decrypted and then traverses the network in plain text

17 How EFS Recovery Works You can configure EFS recovery by using: Data recovery agent Key recovery agent

18 Enterprise Solutions for Managing EFS Deploying a CA allows centralized management of: EFS keys EFS data recovery agents EFS Key Recovery Agents

19 Lesson 3: Implementing and Managing BitLocker What Is BitLocker? BitLocker Requirements BitLocker Modes Using Group Policy Settings to Configure BitLocker Demonstration: Configuring and Using BitLocker Recovering BitLocker-Encrypted Drives Microsoft BitLocker Administration and Monitoring

20 What Is BitLocker? BitLocker encrypts the data that is stored on the operating system and other volumes by: Providing offline data protection Protecting all data stored on the encrypted volume Verifying the integrity of early startup components and boot configuration data Ensuring integrity of the startup process BitLocker to Go allows encryption of removable media such as USB thumb drives

21 BitLocker Requirements BitLocker has the following hardware requirements: A BIOS or UEFI environment that is compatible with a TPM 1.2 or newer device or that supports USB devices during computer startup Enough space on the hard disk for BitLocker to create two partitions

22 BitLocker Modes Windows 10 supports two modes of BitLocker operation: TPM mode: Locks the normal startup process until a user optionally supplies a personal PIN and/or inserts a USB drive that contains a BitLocker startup key Performs system-integrity verification on startup components Non-TPM mode: Uses Group Policy to allow BitLocker to work without a TPM Locks the startup process similar to TPM mode, but the BitLocker startup key must be stored on a USB drive Provides limited authentication

23 Using Group Policy Settings to Configure BitLocker Group Policy provides the following settings for BitLocker: Turn on BitLocker backup in AD DS Configure the recovery folder on Control Panel Setup Enable advanced startup options on Control Panel Setup Configure the encryption method Prevent memory overwrite on restart Configure the TPM validation method used to seal BitLocker keys

24 Recovering BitLocker-Encrypted Drives When a BitLocker-enabled computer starts: BitLocker checks the operating system for conditions that indicate a security risk If a condition is detected: BitLocker enters recovery mode and keeps the system drive locked The user must enter the correct recovery password to continue The BitLocker recovery password: Is a 48-digit password that unlocks a system in recovery mode Is unique to a particular BitLocker encryption Can be stored in AD DS: If stored in AD DS, search for it by using either the drive label or the computer s password

25 Security Settings Available in GPO Common computer security settings that you can configure in Security Options include: Administrator and Guest account names Password policies Access to CD/DVD drives Digital-data signatures Driver-installation behavior Logon prompts UAC AppLocker policies

26 Security Compliance Manager The key features of Security Compliance Manager include: Centralized security baseline management features to manage the security and compliance process efficiently Baselines that are based on Microsoft security guide recommendations and industry best practices Gold master support that allows you to import your existing Group Policy settings for reuse and deployment

27 The Enhanced Mitigation Experience Toolkit The Enhanced Mitigation Experience Toolkit is a tool downloadable from Microsoft s website that allows you to: Apply security vulnerability mitigations on a per application basis Mitigations can be applied to applications on a per-mitigation basis Use SSL/TLS certificate pinning

28 Device Guard and Credential Guard New Windows 10 security features: Device Guard blocks the execution of unauthorized applications Credential Guard stores credentials such as NTLM hashes and Kerberos tickets Both technologies require UEFI Windows 10 Enterprise Edition Virtualization processor extensions and SLAT

29 Mitigations for Network-Related Security Threats It is important to implement a comprehensive approach to network security to ensure that one loophole or omission does not result in another Attack Eavesdropping DoS Port scanning MITM Virus, malicious code Mitigations IPsec, VPNs, intrusion detection Firewalls, perimeter networks, IPsec, server hardening Server hardening, firewalls IPsec, DNSSEC Software updates

30 What Is Windows Firewall?

31 Network Location Profiles Windows 10 uses network location awareness to identify connected networks uniquely Networks can be classified as one of three network location types: Domain Public Private

32 Windows Firewall with Advanced Security

33 Well-Known Ports HTTP (80) HTTPS (443) FTP (21) SMTP (25) POP3 (110) DNS (53) SNMP (161) When an application wants to establish communications with an application on a remote host, it creates a TCP or UDP socket TCP/IP Protocol Suite TCP UDP IPv4 IPv6 Ethernet

34 What Is IPsec? IPsec: Is a suite of protocols that allows secure, encrypted communication between two computers over a unsecured network Has two goals: packet encryption and mutual authentication between systems Enables sending and receiving computers to send secured data to each other Secures network traffic by using encryption and data signing Uses policies to define the type of traffic that IPsec examines, how that traffic is secured and encrypted, and how IPsec peers are authenticated

35 Configuring IPsec Recommended uses of IPsec include: Packet filtering Authenticating and encrypting host-to-host traffic Authenticating and encrypting traffic to specific servers Providing L2TP/IPsec for VPN connections Site-to-site tunneling Enforcing logical networks

36 What Are Connection Security Rules? Connection security rules involve: Authenticating two computers before they begin communications Securing information that is sent between two computers Using key exchange, authentication, data integrity, and data encryption (optionally) How firewall rules and connection rules are related: Firewall rules allow traffic through, but do not secure that traffic Connection security rules can secure the traffic, but depend on a firewall rule to allow traffic through the firewall

37 Authentication Options When using the New Connection Security Rule Wizard to create a new rule, you use the Requirements page to choose one of the following: Option Request authentication for inbound and outbound connections Require authentication for inbound connections and request authentication for outbound connections Require authentication for inbound and outbound connections Description Ask that all inbound/outbound traffic be authenticated, but allow the connection if authentication fails Require that inbound traffic be authenticated, or it will be blocked Outbound traffic can be authenticated, but will be allowed if authentication fails Require that all inbound/outbound traffic be authenticated, or the traffic will be blocked
