/GS is on by default. If you expect your application to have no security exposure, use /GS-. For more information about suppressing buffer overrun detection, see safebuffers.
On functions that the compiler recognizes as subject to buffer overrun problems, the compiler allocates space on the stack before the return address. On function entry, the allocated space is loaded with a security cookie that is computed once at module load. On function exit, and during frame unwinding on 64-bit operating systems, a helper function is called to make sure that the value of the cookie is still the same. A different value indicates that an overwrite of the stack may have occurred. If a different value is detected, the process is terminated.
The /GS compiler option requires that the security cookie be initialized before any function that uses the cookie is run. The security cookie must be initialized immediately on entry to an EXE or DLL. This is done automatically if you use the default VCRuntime entry points: mainCRTStartup, wmainCRTStartup, WinMainCRTStartup, wWinMainCRTStartup, or _DllMainCRTStartup. If you use an alternate entry point, you must manually initialize the security cookie by calling __security_init_cookie.
A vulnerable parameter is allocated before the cookie and local variables. A buffer overrun can overwrite these parameters. And code in the function that uses these parameters could cause an attack before the function returns and the security check is performed. To minimize this danger, the compiler makes a copy of the vulnerable parameters during the function prolog and puts them below the storage area for any buffers.
The /GS compiler option does not protect against all buffer overrun security attacks. For example, if you have a buffer and a vtable in an object, a buffer overrun could corrupt the vtable.
Check Point Software Technologies Ltd. (NASDAQ: CHKP), a leading provider of cyber security solutions globally, today announces a new IoT cyber security technology. Check Point is the first vendor to provide a consolidated security solution that hardens and protects the firmware of IoT devices and makes them secure against the most sophisticated attacks.
The proliferation of Internet-of-things (IoT) devices in Consumer, Enterprise, Industrial and Healthcare organizations, and their inherent security weaknesses, have created a security blind spot where cybercriminals launch 5th and 6th generation of cyber attacks to breach devices (IP camera surveillance), manipulate their operation (medical device infiltration) or even take over critical infrastructure (manufacturing plant) to generate colossal damage.
Secure the Cloud with a unified cloud native security platform, automating security posture at scale, preventing advanced threats and giving you visibility and control over any workload across any cloud.
The second instalment of the 2019 Security Report reveals the key cyber-attack trends observed by Check Point researchers during 2018, and shows the significant growth in stealthy, complex attacks designed to stay below the radar of enterprise security teams. It also shows the types of cyberattacks which enterprise IT and security teams rate as the biggest threats to their organizations. Highlights include:
The following list summarizes the various macro security settings. Under all settings, if antivirus software that works with Microsoft 365 is installed and the workbook contains macros, the workbook is scanned for known viruses before it is opened.
Disable all macros without notification Click this option if you don't trust macros. All macros in documents and security alerts about macros are disabled. If there are documents that contain unsigned macros that you do trust, you can put those documents into a trusted location. Documents in trusted locations are allowed to run without being checked by the Trust Center security system.
Disable all macros with notification This is the default setting. Click this option if you want macros to be disabled, but you want to get security alerts if there are macros present. This way, you can choose when to enable those macros on a case by case basis.
Trust access to the VBA project object model This setting is for developers and is used to deliberately lock out or allow programmatic access to the VBA object model from any Automation client. In other words, it provides a security option for code that is written to automate an Office program and programmatically manipulate the Microsoft Visual Basic for Applications (VBA) environment and object model. This is a per user and per application setting, and denies access by default. This security option makes it more difficult for unauthorized programs to build \"self-replicating\" code that can harm end-user systems. For any Automation client to be able to access the VBA object model programmatically, the user running the code must explicitly grant access. To turn on access, select the check box.
In Excel 2003, all macros are run without restrictions. This security level does not protect against malicious programs, does not allow for acceptance of certificates of trust, and is not considered secure in general. This level is not recommended.
Note We highly recommend that you install the latest security update available. They provide advanced protections from the latest security threats. They also provide capabilities that we have added to support migration. For more information and context about how we are hardening DCOM, see DCOM authentication hardening: what you need to know.
To help you identify the applications that might have compatibility issues after we enable DCOM security hardening changes, we added new DCOM error events in the System log. See the tables below. The system will log these events if it detects that a DCOM client application is trying to activate a DCOM server using an authentication level that is less than RPC_C_AUTHN_LEVEL_PKT_INTEGRITY. You can trace to the client device from the server-side event log and use client-side event logs to find the application.

NSS Labs, Inc. released results for its 2019 Breach Prevention Systems (BPS) Group Test and recognized Check Point Next Generation Threat Prevention Appliance with Endpoint Security as NSS Labs Recommended.
USCIS must collect fingerprint records as part of the background check process on applicants for naturalization regardless of their age. In general, applicants receive a biometric service appointment at a local Application Support Center (ASC) for collection of their biometrics (fingerprints, photographs, and signature).
Previously, USCIS had waived the fingerprint requirements for applicants 75 years old or older because it was difficult to capture readable fingerprints from this age group. As a result, applicants 75 years old or older were not required to appear at an ASC. Electronic processing of applications and improved technology now allows USCIS to capture fingerprints for applicants of all ages and enhances the ability to confirm identity and perform required background checks.
