Not the spray-painting, cow-tipping, annoyance-causing crime we've been seeing over the past few years. Not the viruses and Trojans and DOS attacks for fun and bragging rights. Not even the epidemics that sweep the Internet in hours and cause millions of dollars of damage. Real crime. On the Internet. Crime on the Internet is nothing new. We've all heard isolated stories of competitors breaking into each other's networks, hackers breaking into networks and extorting money from dazed sysadmins, and industrial espionage, identity theft, simple monetary theft from banks and other financial institutions, but it's the Nimdas and the root-name-server attacks that make the headlines. And while we're worrying about those threats, the criminals are slipping by unnoticed. They're stealing money and things they can sell for money. They're stealing credit card numbers and identity information and using it to commit fraud. They're engaging in industrial espionage. The crimes never change; only the tactics are new. I predict that people will start noticing. Companies have a strong self-interest not to publicize any real crime against their networks. The bad press from making an attack public is often more harmful than the attack itself. But the times are changing. Just this year, California passed a law--with large loopholes, unfortunately--requiring companies to make these attacks public. I predict more of these laws in the future. Criminals tend to lag technology by five to ten years, but eventually they figure it out. Just as Willie Sutton robbed banks because "that's where the money is," modern criminals will attack computer networks. Increasingly, value is online instead of in a vault; illicitly changing a number in a database can be more lucrative than staging a robbery. Real crime is hard to detect. When your network is being scanned dozens of times a day by script kiddies, the one serious criminal can sneak in unnoticed. At Counterpane, we monitor hundreds of networks against attack. Our hardest job, and the thing we spend the most time worrying about, is catching the real criminals among the hundreds of annoying hackers.It's the insider trying to change his salary in the human resources computer. It's the robbers trying to manipulate account balances on a bank computer. This is the real crime on the net, and when we catch these guys, our customers are elated. More and more, this is going to be where companies want their computer security dollars to be spent. *********************************************************************** Bill Murray Executive Consultant, TruSecure Corporation Predicting the future can best be done by identifying those trends that are unlikely to change. First, the bad news. Habit, bureaucracy, inertia, and institutional consent to bad practice resist any improvement. The Internet is resistant to all change in the short run; in the long run its security is likely to get worse before it gets better. Small improvements in software quality will be overwhelmed by increases in software. There will continue to be a preference for applications and low price over security in choosing operating systems. [We will continue to complain about Microsoft security while using its products for applications and environments for which they are not intended and do not meet the security requirements.] We will continue to try and patch and fix our way to security; we will continue to fail. Government will continue to chide the private sector while connecting weak systems to the public networks. Business will continue to attach weak systems to public networks in the name of "early to market," "first mover advantage," and ease of operation and management. Government will continue to focus on user-to-user isolation at the operating system layer while authenticating those users only with passwords at the network and application layers. They will continue to prefer mandatory access controls over strict accountability. Government security efforts will continue to focus on preserving its secrets while tolerating fraud, waste, and abuse. Rogue hackers will continue to contaminate the Internet with viruses and worms in the name of improving security while continuing to be lionized by the media as "security experts" and continuing to elude law enforcement. Law enforcement will continue to whine about business' reluctance to share intelligence while abusing and misusing such intelligence as they have. Vulnerability researchers will continue to publish exploits in the name of improving security; the media will continue to refer to them as "security experts." Governments around the world will continue to reward rogue hackers with security job offers; leopards will still not change their spots. Privacy will continue to vary in proportion to the cost of surveillance to the government; that cost will continue to fall. Get used to it. Now for the good news. Economics is on our side. Cheap hardware firewalls, other application appliances, strong authentication, and end-to-end encryption (e.g., SSL, SSH, VPNs) will be used to hide operating system vulnerabilities, privileged controls, sensitive applications, and gratuitous functionality from the public networks. Driven by demand from their customers, threat of government regulation, and competition and example from AOL, retail ISPs and other edge-connectors will take more responsibility for protecting their customers from spam, viruses, DoS, and other attacks and for protecting the rest of us from rude behavior by their users. While users will continue to click on strange files and icons, default use and automatic update of scanners will make us collectively resistant to viruses. Cheap hardware will accelerate the preference for single user and single application systems over multi-user multi-application systems. Led by reluctant heroes like Visa, American Express, and their competitors, and to meet the higher expectations of their customers, e-merchants and e-fiduciaries will continue to improve the security of the applications that they attach to the Internet. Investors, inventors, product vendors, and service providers continue to invest, invent, innovate, provide, and encourage. Government, industry, and professional organizations encourage training, education, commitment, and continuing development of professional knowledge, skills, and abilities. While we will continue to experience attacks and breaches to define the limits of our success, security will continue to be just barely good enough to escape chaos and preserve public trust and confidence. *********************************************************************** Dr. Eugene Spafford Professor and Director, Purdue University CERIAS Here are three predictions: 1) Consumers in the US in particular are going to be drawn into more public debates about on-line privacy. Growing threats of identity theft and spam, along with increasing government interest in data mining and surveillance as well as intrusive DRM schemes by vendors, will all serve to sensitize users to issues of on-line privacy. Although largely unorganized compared to organizations of marketers, music companies and the Attorney General expect a growing political and economic backlash to perceived infringements of perceived and real personal privacy. 2) Sometime in the next year, we will see destructive political cyber attacks. The increasingly strident rhetoric in the international arena will be echoed on the Internet as programmed attacks are developed with a political theme. Some of these will be by long-time malicious code authors, who add the political label as a rationalization, but others will be by newcomers who are radicalized by on-going events. Expect some criminal elements to exploit this opportunistically. Interest in wide-scale IDS and forensics should increase as a result. 3) As a result of #1 and #2, and several vendors, suggesting that they could do with better security, expect to see lawsuits filed for negligence against some major ISPs and vendors. Most will be settled out of court, or dismissed outright, but others will continue. Security firms making claims about the coverage of their products/services will make particularly attractive targets for aggrieved victims since the claims are overstated, and the products not as comprehensive as claimed. North Korea might well be a major flashpoint, possibly requiring additional military presence. If so, it could result in worsening relations with China (as would action in Iraq without UN mandate). India and Pakistan could also boil over if the world's attention were focused elsewhere. Real worst-case here is millions dead and vast areas covered in radioactive by-products. Don't expect the people of China and other countries downwind to be very happy about this and stand by idly if it happens. In addition to widespread destruction, this would also lead to massive starvation because of contaminated crops and mass migration away from contaminated areas. Now, think of where many of our chip fabrication plants are located, and where we get many other computing components. World unrest could easily choke off supply of many critical items, leading to huge shortages in the computing hardware industry. This would also drive down the demand for software. Coupled with lack of consumer confidence from possible terrorist incidents, and a soaring Federal deficit because of tax cuts and increased military spending, we see the possibility of a global economic depression. Regional wars would make this especially severe. To make this even more complete, geologic activity suggests a near-term earthquake of magnitude greater than 7.0 in the SF Bay area. If only a couple of quakes occur offshore, a tsunami would certainly affect Hawaii and points in the Pacific, including Japan. So, why present such a gloomy forecast for 2003? Well, that's worst case. If we make it through the next 12 months without such disasters, with good health and at least some income, we should celebrate Thanksgiving with attitude. Sometimes, we take too much for granted. Best wishes for 2003. *********************************************************************** Stephen Northcutt Director of Education, The SANS Institute There is an old joke about a mathematician during a hotel fire. He wakes up, smells the smoke, grabs his notepad and furiously calculates how much water is needed from the hotel room-drinking cup, and where it needs to be placed. With the problem "solved" he goes back to sleep. I think during 2003 we are going to be tempted to let our guard down just a bit. As a community, we are close to understanding what we need to implement to achieve a reasonable degree of risk management, and some of us will probably mistake knowing what needs to be done for having the problem solved. I learned a new word this week - glicee: it is a digitized picture that looks like an artist's painting -- you can even see brush strokes because the printers used are that advanced. Who in their right mind would ever pay full price for an "original" artwork after knowing how easy it is to produce a perfect copy? It seems that one of the hottest issues in the near future has to be digital rights management. This issue is far more serious and complex than college kids downloading .mp3s. It is not a new issue of course, but it is one that is rapidly growing in importance to both individuals and organizations. A large and rapidly growing part of what we consider valuable -- software, music, money, photographs, movies, art, and the intellectual property that we ourselves have created -- is digital at heart, and can be deleted, modified or copied pretty easily. We need to develop the laws, processes, even terminology to effectively manage and protect digital property. *********************************************************************** Marcus Ranum Consultant, Ranum.com The 5 most important developments to look for in Computer security: 1) Federal IT procurements beginning to put teeth behind standards. Private sector companies have no problem standardizing their firewall access rules and mandating antivirus on desktops. Why can't the feds do likewise? 2) Security companies stop marketing themselves by trumpeting flaws. Soap boxing about vulnerabilities you discover doesn't impress people anymore. 3) The torrent of patches and hotfixes must cease or everyone will start to ignore them and sink into a coma of security-apathy. Vendors: we want products that work -- save the features for later! 4) Standards bodies need to be ahead of the state-of-the-art, not ratifying bodies that bless the technology with the largest installed base. 5) Feds stop using the excuse "but no classified materials were accessed" whenever a government site gets hacked. We all know that unclassified machines contain tons of sensitive information. Stop making excuses and secure those systems! *********************************************************************** Eugene Schultz Principal Engineer with Lawrence Berkeley National Laboratory and faculty member at Univ. of California, Berkeley My predictions for next year include: * The hype concerning cyberterrorism will gradually subside, much the same as the panic over Y2K came and went. * U.S. Presidential panels and commissions will continue to generate a great deal of rhetoric about protecting critical computing infrastructures, but, as in previous years, with little effect. * There will be an increasing demand for appliances that provide security-devices that come preconfigured and ready-to-run. * Worms and viruses will continue to be less successful than they were in previous years because organizations are adopting appropriate measures to counter them. * An abundance of security-related flaws in Microsoft products will continue to emerge; it is still too early for Microsoft's Trusted Computing Initiative to make much of a difference in the security of Microsoft products. * The Digital Millennium Copyright Act (DMCA) will prompt an increasing number of arrests and prosecutions of individuals who discover vulnerabilities in or reverse engineer vendor software. *********************************************************************** Tom Noonan Chairman, President and Chief Executive Officer, Internet Security Systems The IT Security industry is undergoing one of the most dramatic technological periods of advancement it has had in the last five years. The advent of the hybrid threat that began with Code Red and Nimda was a catalyst for this technological revolution. Security measures that rely solely on signatures and port blocking for detecting and/or preventing threats have become obsolete against these threats that pack malicious payloads into trusted or unknown applications. The technology trends that will rise to prominence in 2003 include: 1.Intrusion detection technology advancing into intrusion protection. This technology will combine pattern matching, several layers of protocol analysis, pre-emptive behavioral inspection, anomaly detection and firewall blocking to not only detect online threats, but also to block them altogether. This technology will operate at wire speeds and will reside in-line on network segments as well as on servers and desktops. Most have viewed dynamic detection and prevention systems as the next generation firewall?2003 will be the year that these systems displace static "header" based firewall systems. 2.The integration of vulnerability assessment technology into intrusion protection. There are many advantages to converging these technologies; among them are improved and more timely threat analysis as well as a reduced number of false alarms. A threat against a vulnerable system presents manifest risk; a threat against invulnerable systems is a false positive. Without each other, these systems are under-optimized. 3.Finally, we will see disparate point solutions migrate into a single protection platform. Bringing intrusion protection and vulnerability assessment for networks, servers and desktops under a single architecture will provide for more tightly integrated defense against threats as well as increased ease of security management. 4.The business model changed with e-commerce; the security model did not. 2003 will usher in the realization of a new model and a new era of dynamic protection for every device on the network. Static perimeter defense will give way to modern day dynamic device protection. Core supplanting protection agents will challenge the Cold War-legacy technologies with higher-scale, lower-cost of ownership and more automated and effective protection. Individual protection agents will protect the enterprise systems from the entire spectrum of Internet threats including viruses, malicious content, Trojans, worms, hybrids, unauthorized access and hacking and misuse. *********************************************************************** Gil Shwed Chairman and Chief Executive Officer, Check Point Software Technologies Ltd. Internet security has expanded its role in today's networks. The traditional firewall became the key building block for virtual private networks, connecting a company's branch offices, business partners and remote employees. On-going advances in network connectivity and network attacks that become more sophisticated by the day require a high level of flexibility. In the security market, much emphasis has been placed on "form factor" -- making firewall/VPN devices look and feel like network infrastructure devices. While these are often good qualities, manufacturers tend to drift away from the fundamental challenge - making the Internet secure. In 2003, we see a continued increase in application layer security activities. To address that trend, we need systems that will make security deeper, broader and smarter. Deeper understanding of network protocols is essential. For example, HTTP is no longer used only for web browsing. It has become a transport layer for a variety of applications, from instant messaging to business transactions. Technologies like Application Intelligence are required to safeguard corporate networks from violation through application layer vulnerabilities. Broader deployment of network security is essential. With the proliferation of Internet connectivity, broadband (always on) networks, wireless LANs and cellular networks, the scope of network security is expanding beyond the traditional security perimeter. Technology to consistently manage and enforce security policies must be deployed both in front of and behind the perimeter to secure all access points. Smarter security decisions are a crucial element as a mix of security technologies are deployed more broadly. Active Defense technologies allow an attack detected in one part of the network to be instantly avoided at other access points. A distributed security model requires the ability to make sense of the enormous volume of raw data generated in a typical enterprise network security deployment. A firewall/VPN system alone can collect five to ten million records per day in a mid-size corporation. Technologies to analyze, correlate, and translate this data into action are essential. These changes in the security marketplace--deeper understanding of attacks, broader deployment of security, and smarter analysis --will enable organizations to ensure comprehensive network security. *********************************************************************** Rob Clyde VP & Chief Technology Officer, Symantec Corporation Over the next year, we will likely see developments in the following areas affecting security, for users across the world. New Attackers It is clear that our global economy is increasingly dependent on the Internet. Online machines now control numerous, crucial infrastructure elements of our society, including financial transactions, power generation, business supply chains, and many others. Until now, most of the highest-profile attacks on the Internet have been undertaken by "amateurs", young people with no particular motivation or target in mind. However, we expect that over the coming year and beyond, we will see a rise in more "professional" types of attackers, targeting specific, crucial online systems and posing great potential dangers not only to the Internet, but also to our national security, and our entire way of life. New Platforms Over the coming year and beyond, there will be continued growth of new systems on the Internet. In particular, we believe that home broadband, instant messaging, wireless communications, and business-to-business web services will all become progressively more widespread. All of these technologies are highly connected, and if not properly secured, could serve as increasingly important conduits or targets for attacks on the Internet. Appropriate security will be crucial to reaping the full benefits of these systems as their popularity grows. New Protection Many of today's security solutions are geared towards the detection of "known" attacks (attacks which researchers have previously analyzed). Furthermore, these systems often focus on detecting such attacks, but are less capable of mitigation and prevention. While reactive approaches will never go away, the security industry is actively investing in proactive systems that can provide first-strike protection against all categories of Internet-based threats. We expect to see the emergence and initial deployment of such new proactive technologies in the year ahead. *********************************************************************** Greg Akers and John N. Stewart Greg Akers, SVP, CTO Security and Strategic Services, Cisco Systems John Stewart, Director, Information Security, Cisco Systems Security, both awareness and interest, will continue on its upward trend for 2003. As organizations face increasing attacks, both in frequency and complexity, they will impose a related increased demand from providers and vendors to answer the challenges faced. As individuals suffer lost productivity and increased annoyance, they will demand answers from their providers. On the technology front, intrusion detection will move from a detection/reactive market (IDS) to a protective market. Adaptation methods will begin to protect against an attack as opposed to just warning of one. The solutions will be in cooperative technologies -- where a proactive system talks to the defensive system and combined, they mitigate attacks and require lower human intervention. Mobility will continue to change the face of security. Traditional methods to protect can no longer be only network based, but must push protection to include host and application. The lines between what a device is and how it is used are blurring. A cell phone is rapidly becoming a hand held computer, connected both by cellular technology and by IP. A phone is rapidly becoming a laptop, or a microcode and Java driven application platform. These devices can be infected by a virus, worm and can ultimately become a weapon. A worm can affect IP phones. Perimeter protecting with firewalls isn't the only solution. Protecting with Defense In Depth, where application, host, and network work in concert, is essential at multiple levels. It will be the busiest year yet in precedent-setting cases for Internet attack damages, liability for ISPs, loss of productivity due to such things as abusive email, how to recoup lost revenue when a DDoS attack is launched. The question will be: what will be the total cost and impact of these attacks? ===end=== Edited by: Alan Paller and Barbara Rietveld Please feel free to share this with interested parties via email, but no posting is allowed on web sites.
