[How Safe Is Your PC Against Advanced Security Threats
Virginie Fayad
Windows 10 and 11 include Windows Security, which provides the latest antivirus protection. Your device will be actively protected from the moment you start Windows. Windows Security continually scans for malware (malicious software), viruses, and security threats. In addition to this real-time protection, updates are downloaded automatically to help keep your device safe and protect it from threats.
Windows Security is built-in to Windows and includes an antivirus program called Microsoft Defender Antivirus. (In early versions of Windows 10, Windows Security is called Windows Defender Security Center).
If you have another antivirus app installed and turned on, Microsoft Defender Antivirus will turn off automatically. If you uninstall the other app, Microsoft Defender Antivirus will turn back on automatically.
Virus & threat protection - Monitor threats to your device, run scans, and get updates to help detect the latest threats. (Some of these options are unavailable if you're running Windows 10 in S mode.)
App & browser control - Update settings for Microsoft Defender SmartScreen to help protect your device against potentially dangerous apps, files, sites, and downloads. You'll have exploit protection and you can customize protection settings for your devices.
Sometimes you may need to briefly stop running real-time protection. While real-time protection is off, files you open or download won't be scanned for threats. However, real-time protection will soon turn on automatically again to protect your device.
Advanced Threat Protection provides the insight you need to stop and respond to today's advanced threats. Apply fully verified threat intelligence that includes proof of conviction, data on more than 40 threat categories, five-year history, and related samples, domains, and IPs.
Avoid alert fatigue with Advanced Threat Protection. Investigate, prioritize and verify the threats that matter. Respond faster to incidents by automating and streamlining manual tasks. Manage incidents across your entire security infrastructure in a single view.
Security measures begin long before you arrive at the airport. TSA works closely with the intelligence and law enforcement communities to share information. Additional security measures are in place from the time you get to the airport until you get to your destination.
TSA adjusts processes and procedures to meet the evolving threat and to achieve the highest levels of transportation security. Because of this, you may notice changes in our procedures from time to time.
Electronics
You will be asked to remove personal electronic devices larger than a cell phone from your carry-on bag and place them into a bin with nothing placed on or under them for X-ray screening.
Food
Listen to the instructions of the TSA officer. In most cases, food or snacks such as fruit, health bars, and sandwiches can stay inside your carry-on bag. There are special instructions for liquids, gels, and aerosols, as well as for baby food, breast milk and medically necessary items.
Packing
If you are preparing for your flight, be aware that how and what you pack can impact the screening process. Be sure that you check for prohibited items and remember to follow the 3-1-1 liquids rule.
In addition to screening personal electronic devices separately, including laptops, tablets, e-readers and handheld game consoles, TSA officers may instruct travelers to separate other items from carry-on bags such as foods, powders, and any materials that can clutter bags and obstruct clear images on the X-ray machine.
TSA screens approximately 1.3 million checked bags for explosives and other dangerous items daily. Upon check in, your checked baggage will be provided to TSA for security screening. Once the screening process has completed, your airline will transport your checked baggage on your respective flight as well as deliver it to the baggage claim area. The majority of checked baggage is screened without the need for a physical bag search.
Inspection Notices: TSA may inspect your checked baggage during the screening process. If your property is physically inspected, TSA will place a notice of baggage inspection inside your bag. This is to inform you that an officer conducted an inspection of your property.
Claims: If your property is lost or damaged during the screening process, you may file a claim with TSA. If your property is lost or damaged during transport to the plane or baggage claim, please contact your airline.
Locks: TSA has been provided universal "master" keys under agreements with Safe Skies Luggage Locks and Travel Sentry so that certain branded locks may not have to be cut to inspect baggage. These locks are commercially available, and packaging on the locks should indicate they may be opened by TSA officers. TSA has no position on the validity or effectiveness of these product as a security measure and will be forced to remove these products if necessary during the inspection.
Monitoring: Responsibilities for access control and video monitoring of checked baggage facilities fall to individual airports as part of their security plan. Methods of monitoring vary from airport to airport and may include CCTV.
The U.S. Department of Homeland Security is actively working to raise the baseline for aviation security across the globe by requiring the implementation of enhanced security measures, both seen and unseen, at approximately 280 foreign airports with direct commercial flights to the U.S., in more than 100 countries around the world. Read about the security measures and FAQ for more information on aviation security worldwide.
What to Expect
If you are flying from any of the last-point-of-departure airports into the U.S., you may experience a more extensive screening process and should prepare for additional screening of your property and personal electronic devices. We recommend arriving early to the airport to allow enough time for the screening process. Please know, there are no changes to items allowed in carry-on and checked baggage.
For your convenience, we encourage you to place powder-like substances over 12 oz. / 350 mL in your checked bags. Powders in carry-on baggage may require secondary screening, and powders that cannot be resolved by security officials will be prohibited from the cabin of the aircraft effective June 30, 2018.
Hazardous Materials
Most hazardous materials are forbidden in carry-on and checked baggage. There are a few exceptions for some personal items such as toiletries, medicines, battery powered electronics and assistive devices. To learn about transporting hazardous materials to the U.S., check the Federal Aviation Administration Pack Safe list.
A pat-down may include inspection of the head, neck, arms, torso, legs, and feet. This includes head coverings and sensitive areas such as breasts, groin, and the buttocks. You may be required to adjust clothing during the pat-down. The officer will advise you of the procedure to help you anticipate any actions before you feel them. Pat-downs require sufficient pressure to ensure detection, and areas may undergo a pat-down more than once for the TSA officer to confirm no threat items are detected.
TSA officers use the back of the hands for pat-downs over sensitive areas of the body. In limited cases, additional screening involving a sensitive area pat-down with the front of the hand may be needed to determine that a threat does not exist.
You will receive a pat-down by an officer of the same gender. TSA officers will explain the procedures to you as they conduct the pat-down. Please inform an officer if you have difficulty raising your arms or remaining in the position required; an external medical device; or areas of the body that are painful when touched. You may request a chair to sit if needed.
TSA uses millimeter wave advanced imaging technology and walk-through metal detectors to screen passengers. Millimeter wave advanced imaging technology safely screens passengers without physical contact for metallic and non-metallic threats, including weapons and explosives, which may be concealed under clothing. Generally, passengers undergoing screening will have the opportunity to decline AIT screening in favor of physical screening. However, some passengers will be required to undergo AIT screening if their boarding pass indicates that they have been selected for enhanced screening, in accordance with TSA regulations, prior to their arrival at the security checkpoint. This will occur in a very limited number of circumstances. The vast majority of passengers will not be affected. See the responses to frequently asked questions.
Safety: Advanced imaging technology is safe and meets national health and safety standards. This technology uses non-ionizing radio-frequency energy in the millimeter spectrum with no known adverse health effects. It does not use X-ray technology.
Privacy: TSA has strict privacy standards when using advanced imaging technology to protect your privacy. Advanced imaging technology uses automated target recognition software that eliminates passenger-specific images and instead auto-detects potential threats by indicating their location on a generic outline of a person. The generic outline is identical for all passengers.
Light Outer Garment / Bulky Clothing: Any individual wearing a light outer garment or bulky clothing when screened through Advanced Imaging Technology (AIT) will be asked to divest their light outwear or bulky clothing. A light outer garment is defined as an outer layer of clothing which has a full front zipper or buttons used to fasten the outer garment, excluding button shirts. Examples include, but are not limited to, windbreakers and vests, suit/sport coats, blazers, and light jackets. Bulky clothing is a garment that is very loose or doesn't conform to the contour of the person. Examples include but are not limited to, oversize pullover hoodies, large sweaters, cardigans, and ponchos. If an individual cannot or is not willing to remove a light outer garment or bulky clothing, let the officer know and additional screening may occur.
