Our experiments demonstrate that cache-based geolocation can achieve at least accurate country-level granularity in the regions where CDN edge servers are densely deployed. To evaluate the usability and accuracy of the cache-based user geolocation, we conducted practical experiments based on a commercial VPN with over 160 endpoints distributed in 94 countries. As a result, a website can infer coarse-grained user location by asking a user to send an HTTP request to an arbitrary domain that is known being served by a CDN, and inspecting the corresponding responses. Many of these edge servers are assigned with unique identifiers that are tied to their location, which can be easily retrieved by inspecting HTTP responses headers served by these edge servers. This work is motivated by the fact that CDN providers deploy a number of edge servers that are geographically distributed across the world. In this paper, we propose a novel approach, namely CacheLoc, for coarse-grained user geolocation leveraging widely-deployed content delivery networks (CDNs). However, besides Internet giants such as Google, who retains a large amount of detailed user information, most websites still rely on IP addresses for user geolocation, which is proven inaccurate and misleading by existing studies. In nowadays’ Internet, websites rely more and more on obtaining users’ geolocation to provide customized services. EASs will be positioned to update critical infrastructure, notify groups of emergencies, and ensure the distribution of valid and reliable information to the populations at risk. We recommend integrated policies and procedures at all levels of the public-private-government partnerships, along with system resilience, as lines of defense against cybersecurity threats. To identify, prioritize, and address EAS vulnerabilities, we present a list of technical and management strategies to reduce cybersecurity threats. Next, we searched for published policies on the reporting of vulnerabilities we found no vulnerability disclosure policies for any of the systems identified. We found 18 such websites that were accessible via the Internet, only requiring user credentials to login to the system. EASs, we used Shodan to evaluate the availability of these websites in six southeastern states. Other concerns exist, primarily the lack of policies for reporting vulnerabilities. Authorities must secure these systems quickly. Some EASs have an easily identifiable vulnerability - their management website is available via the Internet. These systems are built on aging platforms and suffer from a fragmented interconnected network of partnerships. emergency alert systems (EASs) are part of the nation's critical infrastructure. In this paper we will look at applications and methodologies (both traditional and more recent) for IP Geolocation. The ability to determine the exact location of a person connecting over the Internet can not only lead to innovative location based services but it can also dramatically optimise the shipment of data from end to end. If the user consents then the service can view your ISP's logs and track you as accurately as possible. In some countries laws are in place that state a service can only track you as far as your country without your consent. This method of tracking can have very broad results and can sometimes only get an accurate result with some input from the user about their location. The IP address of a device is unique to that device and as such the location can be narrowed down from the continent to the country and even to the street address of the device. This can have many potential benefits for business and other types of application. IP Geolocation allows us to assign a geographical location to an IP address allowing us to build up a picture of the person behind that IP address.
